Measurements of the charged-particle distributions at p s = 8 and 13 TeV with the ATLAS detector
November 09, 2016
Inclusive charged-particle measurements at hadron colliders probe the low-energy non-perturbative region of QCD. The ATLAS collaboration has measured the primary-charged-particle multiplicity and its dependence on transverse momentum and pseudorapidity in special data sets with low LHC proton--proton beam currents, recorded at centre-of-mass energies of 8 TeV and 13 TeV. The new precise measurements at 8 TeV cover a wide spectrum of distributions using charged-particle selections with minimum transverse momentum of both 100 MeV and 500 MeV and in various phase-space regions of low and high charged-particle multiplicities. Two measurements at 13 TeV present the first detailed studies with a minimum transverse momentum of 500 MeV and 100 MeV. The measurements are compared with predictions of various MC generators and are found to provide strong constraints on these.
