### ALEPH_1991_S2435284

Hadronic Z decay charged multiplicity measurement
Experiment: ALEPH (LEP 1)
Spires ID: 2435284
Status: VALIDATED
Authors:

- Andy Buckley

References:

- Phys. Lett. B, 273, 181 (1991)

Beams: e+ e-
Beam energies: (45.6, 45.6)GeV
Run details:

- Hadronic Z decay events generated on the Z pole (sqrt(s) = 91.2 GeV)

The charged particle multiplicity distribution of hadronic Z decays, as measured on the peak of the Z resonance using the ALEPH detector at LEP. The unfolding procedure was model independent, and the distribution was found to have a mean of 20.85 +- 0.24, Comparison with lower energy data supports the KNO scaling hypothesis. The shape of the multiplicity distribution is well described by a log-normal distribution, as predicted from a cascading model for multi-particle production.

### ALEPH_1996_S3196992

Measurement of the quark to photon fragmentation function
Experiment: ALEPH (LEP Run 1)
Spires ID: 3196992
Status: VALIDATED
Authors:

- Frank Siegert

References:

- Z.Phys.C69:365-378,1996

Beams: e+ e-
Beam energies: (45.6, 45.6)GeV
Run details:

- e^+e^-\to jets with \pi and \eta decays turned off.

Earlier measurements at LEP of isolated hard photons in hadronic Z decays, attributed to radiation from primary quark pairs, have been extended in the ALEPH experiment to include hard photon production inside hadron jets. Events are selected where all particles combine democratically to form hadron jets, one of which contains a photon with a fractional energy z > 0.7. After statistical subtraction of non-prompt photons, the quark-to-photon fragmentation function, D(z), is extracted directly from the measured 2-jet rate.

- Inelastic events (non-diffractive and inelastic diffractive).

Measurements of cross-sections of inelastic and diffractive processes in proton-proton collisions at \sqrt{s} = 900, 2760 and 7000 GeV. The fractions of diffractive processes in inelastic collisions were determined from a study of gaps in charged particle pseudorapidity distributions. Single-diffractive events are selected with M_{X} < 200\;\GeV/c^2 and double-diffractive events defined as NSD events with \Delta\eta > 3. To measure the inelastic cross-section, beam properties were determined with van der Meer scans using a simulation of diffraction adjusted to data. Note that these are experimental approximations to theoretical concepts -- it is not totally clear whether the data point values are model-independent.

The underlying event measurements with the ATLAS detector at the LHC at the center of mass energies of 900 GeV and 7 TeV. The observables sensitive to the underlying event, i.e the charged particle density and charged pT sum, as well as their standard deviations and the average pT, are measured as functions of the leading track. A track pT cut of 500 MeV is applied for most observables, but the main profile plots are also shown for a lower track cut of 100 MeV, which includes much more of the soft cross-section. The angular distribution of the charged tracks with respect to the leading track is also studied, as are the correlation between mean transverse momentum and charged particle multiplicity, and the `plateau' height as a function of the leading track |\eta|.

Measurements in different regions of phase-space are shown, providing diffraction-reduced measurements as well as more inclusive ones. The observed distributions are corrected to well-defined phase-space regions, using model-independent corrections.

The production of Kshort and Lambda hadrons is studied in inelastic pp collisions at sqrt(s) = 0.9 and 7 TeV collected with the ATLAS detector at the LHC using a minimum-bias trigger. The observed distributions of transverse momentum, rapidity, and multiplicity are corrected to hadron level in a model-independent way within well defined phase-space regions. The distribution of the production ratio of Lambdabar to Lambda baryons is also measured. The results are compared with various Monte Carlo simulation models. Although most of these models agree with data to within 15% in the Kshort distributions, substantial disagreements with data are found in the Lambda distributions of transverse momentum.

- Require QCD interactions at 7TeV. A substantial number of events are required to populate the large rapidity seperation region.

A measurement of the jet activity in rapidity intervals bounded by a dijet system. The fraction of events passing a veto requirement are shown as a function of both the rapidity interval size and the average transverse momentum of the dijet system. The average number of jets above the veto threshold are also shown as a function of the same variables. There are two possible selection criteria applied to data. Either the two highest transverse momentum jets or the jets most forward and backward in rapidity are taken to define the dijet system, where the veto threhsold is 20GeV. Additionally for the latter selection an alternative veto transverse momentum threshold which is equal to the average transverse momentum is applied. Jet selections are based on anti-kt with R=0.6, p_\perp>20 GeV and |y|<4.4.

The Z pT at \sqrt{s} = 7\;TeV is measured using electron and muon Z decay channels. The dressed leptons definition uses photons clustered in a cone around the charged leptons, while the bare lepton definition uses the post-FSR charged leptons only in the Z reconstruction. The data used in the bare leptons calculation are based on a forward application of a PHOTOS-based energy loss correction and are hence not quite model-independent.

- QCD jet production with a minimum leading jet pT of 30 GeV and minimum second jet pT of 20 GeV at 7 TeV.

Inclusive jet and dijet cross sections have been measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector at the Large Hadron Collider. The cross sections were measured using jets clustered with the anti-kT algorithm with parameters R=0.4 and R=0.6. These measurements are based on the 2010 data sample, consisting of a total integrated luminosity of 37 inverse picobarns. Inclusive jet double-differential cross sections are presented as a function of jet transverse momentum, in bins of jet rapidity. Dijet double-differential cross sections are studied as a function of the dijet invariant mass, in bins of half the rapidity separation of the two leading jets. The measurements are performed in the jet rapidity range |y|<4.4, covering jet transverse momenta from 20 GeV to 1.5 TeV and dijet invariant masses from 70 GeV to 5 TeV. This is the successor analysis of ATLAS_2010_S8817804

- Minimum bias inelastic pp collision at 7 TeV including diffractive component and overall cross section.

Pseudorapidity gap distributions in proton-proton collisions at sqrt(s) = 7 TeV are studied using a minimum bias data sample with an integrated luminosity of 7.1 inverse microbarns. Cross sections are measured differentially in terms of Delta eta F, the larger of the pseudorapidity regions extending to the limits of the ATLAS sensitivity, at eta = +/- 4.9, in which no final state particles are produced above a transverse momentum threshold p_T Cut. The measurements span the region 0 < Delta eta F < 8 for 200 < p_T Cut < 800 MeV. At small Delta eta F, the data test the reliability of hadronisation models in describing rapidity and transverse momentum fluctuations in final state particle production. The measurements at larger gap sizes are dominated by contributions from the single diffractive dissociation process (pp -> Xp), enhanced by double dissociation (pp -> XY) where the invariant mass of the lighter of the two dissociation systems satisfies M_Y <~ 7 GeV. The resulting cross section is d sigma / d Delta eta F ~ 1 mb for Delta eta F >~ 3. The large rapidity gap data are used to constrain the value of the pomeron intercept appropriate to triple Regge models of soft diffraction. The cross section integrated over all gap sizes is compared with other LHC inelastic cross section measurements.

Measurement of the ordering of charged hadrons in the azimuthal angle relative to the beam axis at the Large Hadron Collider (LHC). A spectral analysis of correlations between longitudinal and transverse components of the momentum of the charged hadrons is performed. Data were recorded with the ATLAS detector at centre-of-mass energies of \sqrt{s} = \unit{900}{\GeV} and \sqrt{s} = \unit{7}{\TeV}. The correlations measured in a phase space region dominated by low-pT particles are not well described by conventional models of hadron production. The measured spectra show features consistent with the fragmentation of a QCD string represented by a helix-like ordered gluon chain.

Pseudorapidity distributions based on the CDF 630 and 1800 GeV runs from 1987. All data is detector corrected. The data confirms the UA5 measurement of a \d{N}/\d{\eta} rise with energy faster than \ln{\sqrt{s}}, and as such this analysis is important for constraining the energy evolution of minimum bias and underlying event characteristics in MC simulations.

CDF Run I color coherence analysis. Events with \ge 3 jets are selected and Et distributions of the three highest-pT jets are obtained. The plotted quantities are the \Delta{R} between the 2nd and 3rd leading jets in the pT and pseudorapidity of the 3rd jet, and \alpha = \mathrm{d}{\eta}/\mathrm{d}{\phi}, where \mathrm{d}{\eta} is the pseudorapidity difference between the 2nd and 3rd jets and \mathrm{d}{\phi} is their azimuthal angle difference. Since the data has not been detector-corrected, a bin by bin correction is applied, based on the distributions with ideal and CDF simulation as given in the publication.

Measurement of transverse momentum and total cross section of e^+e^- pairs in the Z-boson region of 66~\text{GeV}/c^2 < m_{ee} < 116~\text{GeV}/c^2 from pbar-p collisions at sqrt(s) = 1.8 TeV, with the Tevatron CDF detector. The Z pT, in a fully-factorised picture, is generated by the momentum balance against initial state radiation (ISR) and the primordial/intrinsic pT of the Z's parent partons in the incoming hadrons. The Z pT is important in generator tuning to fix the interplay of ISR and multi-parton interactions (MPI) ingenerating `underlying event' activity. This analysis is subject to ambiguities in the experimental Z pT definition, since the Rivet implementation reconstructs the Z momentum from the dilepton pair with finite cones for QED bremstrahlung summation, rather than non-portable direct use of the (sometimes absent) Z in the event record.

- p\bar{p} QCD interactions at 1800 GeV. The leading jet is binned from 0--49 GeV, and histos can usually can be filled with a single generator run without kinematic sub-samples.

The original CDF underlying event analysis, based on decomposing each event into a transverse structure with ``toward'', ``away'' and ``transverse'' regions defined relative to the azimuthal direction of the leading jet in the event. Since the toward region is by definition dominated by the hard process, as is the away region by momentum balance in the matrix element, the transverse region is most sensitive to multi-parton interactions. The transverse regions occupy |\phi| \in [60\degree, 120\degree] for |\eta| < 1. The pT ranges for the leading jet are divided experimentally into the `min-bias' sample from 0--20 GeV, and the `JET20' sample from 18--49 GeV.

- QCD events at sqrt(s) = 630 and 1800 GeV.

A study of p\bar{p} collisions at sqrt(s) = 1800 and 630 GeV collected using a minimum bias trigger in which the data set is divided into two classes corresponding to `soft' and `hard' interactions. For each subsample, the analysis includes measurements of the multiplicity, transverse momentum (pT) spectra, and the average pT and event-by-event pT dispersion as a function of multiplicity. A comparison of results shows distinct differences in the behavior of the two samples as a function of the center of mass energy. The properties of the soft sample are invariant as a function of c.m. energy. It should be noticed that minimum bias tunings of PYTHIA made by ATLAS in early 2010, which used this among all other available data from CDF and from ATLAS at 900~GeV and 7~TeV, found an unavoidable tension between this data and the rest. Accordingly, this data was excluded from the fits. Whether this reflects a problem with this dataset or with the PYTHIA MPI model is a judgement for users to make!

Run details:

- QCD events at sqrt(s) = 630 & 1800 GeV. Several pTmin cutoffs are probably required to fill the profile histograms, e.g. 0 (min bias), 30, 90, 150 GeV at 1800 GeV, and 0 (min bias), 20, 90, 150 GeV at 630 GeV.

This analysis studies the underlying event via transverse cones of R = 0.7 at 90 degrees in \phi relative to the leading (highest E) jet, at sqrt(s) = 630 and 1800 GeV. This is similar to the 2001 CDF UE analysis, except that cones, rather than the whole central \eta range are used. The transverse cones are categorised as TransMIN and TransMAX on an event-by-event basis, to give greater sensitivity to the UE component. `Swiss Cheese' distributions, where cones around the leading n jets are excluded from the distributions, are also included for n = 2, 3. This analysis is useful for constraining the energy evolution of the underlying event, since it performs the same analyses at two distinct CoM energies. WARNING! The pT plots are normalised to raw number of events. The min bias data have not been reproduced by MC, and are not recommended for tuning.

Deepak Kar and Rick Field's measurement of the underlying event in Drell-Yan events.

The reconstructed Z defines the \phi direction of the toward region. The leptons are ignored after the Z has been reconstructed. Thus the region most sensitive to the underlying event is the toward region (the recoil jet is boosted into the away region).

Measurement of the b-jet production cross section for events containing a Z boson produced in p\bar{p} collisions at \sqrt{s}=1.96 TeV, using data corresponding to an integrated luminosity of 2 fb^{-1} collected by the CDF II detector at the Tevatron. Z bosons are selected in the electron and muon decay modes. Jets are considered with transverse energy E_T>20 GeV and pseudorapidity |\eta|<1.5. The ratio of the integrated Z + b-jet cross section to the inclusive Z production cross section is measured differentially in jet E_T, jet \eta, Z-boson transverse momentum, number of jets, and number of b-jets. The first two measurements have an entry for each b-jet in the event, the last three measurements have one entry per event.

Deepak Kar and Rick Field's measurement of the underlying event in Drell-Yan events. Z -> ee and Z -> \mu\mu events are selected using a Z mass window cut between 70 and 110~GeV. ``Toward'', ``away'' and ``transverse'' regions are defined in the same way as in the original (2001) CDF underlying event analysis. The reconstructed Z defines the \phi direction of the toward region. The leptons are ignored after the Z has been reconstructed. Thus the region most sensitive to the underlying event is the toward region (the recoil jet is boosted into the away region).

A measurement of the underlying event activity using Drell-Yan events using muonic final state. The production of charged particles with pseudorapidity |\eta| < 2 and transverse momentum p_\perp > 0.5\,\GeV/c is studied in towards, transverse and away region w.r.t. to the direction of di-muon system. The UE activity is measured in terms of of a particle density and an energy density. The particle density is computed as the average number of primary charged particles per unit pseudorapidity and per unit azimuth. The energy density is expressed in terms of the average of the scalar sum of the transverse momenta of primary charged particles per unit pseudorapidity and azimuth. The ratio of the energy and particle density is also reported in 3 regions. UE activity is studied as a function of invariant mass of muon pair (M_{\mu\mu}) by limiting the ISR contribution by requiring transverse momentum of muon pair p_\perp(\mu\mu) < 5\,\GeV/c. The p_\perp(\mu\mu) dependence is studied for the events having M_{\mu\mu} in window of 81--101 GeV/c. The normalized charged particle multiplicity and p_\perp spectrum of the charged particles in three regions also been reported for events having M_{\mu\mu} in window of 81--101 GeV/c. Multiplicity and p_\perp spectra in the transverse region are also reported, for events having p_\perp(\mu\mu) < 5\,\GeV/c.

The process p \bar{p} -> photon + jet + X as studied by the D0 detector at the Fermilab Tevatron collider at center-of-mass energy sqrt(s) = 1.96 TeV. Photons are reconstructed in the central rapidity region |y_\gamma| < 1.0 with transverse momenta in the range 30--400 GeV, while jets are reconstructed in either the central |y_\text{jet}| < 0.8 or forward 1.5 < |y_\text{jet}| < 2.5 rapidity intervals with pT^\text{jet} > 15~\text{GeV}. The differential cross section \mathrm{d}^3 \sigma / \mathrm{d}{pT^\gamma} \mathrm{d}{y_\gamma} \mathrm{d}{y_\text{jet}} is measured as a function of pT^\gamma in four regions, differing by the relative orientations of the photon and the jet.

This data is sensitive to proton parton distribution functions due to the valence asymmetry in the incoming quarks which produce the W. Initial state radiation should also affect the pT distribution.

First measurements at a hadron collider of differential cross sections for Z (\to \mu\mu)+jet+X production in \Delta\phi(Z, j), |\Delta y(Z, j)| and |y_\mathrm{boost}(Z, j)|. Vector boson production in association with jets is an excellent probe of QCD and constitutes the main background to many small cross section processes, such as associated Higgs production. These measurements are crucial tests of the predictions of perturbative QCD and current event generators, which have varied success in describing the data. Using these measurements as inputs in tuning event generators will increase the experimental sensitivity to rare signals.

Direct photon pair production cross sections are measured using 4.2 fb^{-1} of data. They are binned in diphoton mass, the transverse momentum of the diphoton system, the azimuthal angle between the photons, and the polar scattering angle of the photons. Also available are double differential cross sections considering the last three kinematic variables in three diphoton mass bins. Note, the numbers in version 1 of the arXiv preprint were missing the dM normalisation in the double differential cross sections. This has been reported to and fixed by the authors in v2 and the journal submission. HepData as well as the Rivet analysis have also been updated.

Energy flows in both the laboratory frame and the hadronic centre of mass system, and energy-energy correlations in the laboratory frame are presented. Historically, the Ariadne colour dipole model provided the only satisfactory description of this data, hence making it a useful 'target' analysis for MC shower models.

- e^+ p deep inelastic scattering with p at 820 GeV, e^+ at 27.5 GeV -> sqrt(s) = 300 GeV

Measurements of transverse energy flow for neutral current deep- inelastic scattering events produced in positron-proton collisions at HERA. The kinematic range covers squared momentum transfers Q^2 from 3.2 to 2200 GeV^2; the Bjorken scaling variable x from 8 \times 10^{-5} to 0.11 and the hadronic mass W from 66 to 233 GeV. The transverse energy flow is measured in the hadronic centre of mass frame and is studied as a function of Q^2, x, W and pseudorapidity. The behaviour of the mean transverse energy in the central pseudorapidity region and an interval corresponding to the photon fragmentation region are analysed as a function of Q^2 and W. This analysis is useful for exploring the effect of photon PDFs and for tuning models of parton evolution and treatment of fragmentation and the proton remnant in DIS.

UE analysis similar to Rick Field's leading jet analysis. SIScone with radius/resolution parameter R=0.7 is used. Particles with pT > 0.2~\text{GeV} and |\eta| < 1 are included in the analysis. All particles are assumed to have zero mass. Only jets with neutral energy < 0.7 are included. For the transMIN and transMAX \Delta(\phi) is between \pi/3 and 2\pi/3, and \Delta(\eta) < 2.0. For the jet region the area of the jet is used for the normalization, i.e. the scaling factor is \pi R^2 and not \mathrm{d}\phi\mathrm{d}\eta (this is different from what Rick Field does!). The tracking efficiency is \sim 0.8, but that is an approximation, as below pT \sim 0.6~\text{GeV} it is falling quite steeply.

- ppbar events. Non-single diffractive events need to be switched on. The trigger implementation is the same as in UA5_1989_S1926373. Important: Only the correlation strengths with symmetric eta bins should be used for tuning.

Data on two-particle pseudorapidity and multiplicity correlations of charged particles for non single-diffractive \bar{p}p collisions at c.m. energies of 200, 546 and 900 GeV. Pseudorapidity correlations interpreted in terms of a cluster model, which has been motivated by this and other experiments, require on average about two charged particles per cluster. The decay width of the clusters in pseudorapidity is approximately independent of multiplicity and of c.m. energy. The investigations of correlations in terms of pseudorapidity gaps confirm the picture of cluster production. The strength of forward-backward multiplicity correlations increases linearly with ins and depends strongly on position and size of the pseudorapidity gap separating the forward and backward interval. All our correlation studies can be understood in terms of a cluster model in which clusters contain on average about two charged particles, i.e. are of similar magnitude to earlier estimates from the ISR.

Multiplicity distributions of charged particles produced in non-single-diffractive collisions between protons and antiprotons at centre-of-mass energies of 200 and 900 GeV. The data were recorded in the UA5 streamer chambers at the CERN collider, which was operated in a pulsed mode between the two energies. This analysis confirms the violation of KNO scaling in full phase space found by the UA5 group at an energy of 546 GeV, with similar measurements at 200 and 900 GeV.
