内容記述
The pseudorapidity (η) and transverse-momentum (pT) distributions of charged particles produced in proton–proton collisions are measured at the centre-of-mass energy √s=13TeV. The pseudorapidity distribution in |η|<1.8is reported for inelastic events and for events with at least one charged particle in |η|<1. The pseudorapidity density of charged particles produced in the pseudorapidity region |η|<0.5is 5.31 ±0.18 and 6.46 ±0.19for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 <pT<20GeV/cand |η|<0.8for events with at least one charged particle in |η|<1. The evolution of the transverse momentum spectra of charged particles is also investigated as a function of event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators.
