Pseudorapidity and transverse-momentum distributions of charged particles in proton-proton collisions at $\sqrt{\text{s}}$ = 13 TeV

Abstract

The pseudorapidity ($\eta$) and transverse-momentum ($p_{\mathrm{T}}$) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy $\sqrt{s}$ = 13 TeV. The pseudorapidity distribution in $|\eta |<$ 1.8 is reported for inelastic events and for events with at least one charged particle in $|\eta |<$ 1. The pseudorapidity density of charged particles produced in the pseudorapidity region $|\eta |<$ 0.5 is 5.31 $\pm$ 0.18 and 6.46 $\pm$ 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 $<$ $p_{\mathrm{T}}$ $<$ 20 GeV/c and $|\eta |<$ 0.8 for events with at least one charged particle in $|\eta |<$ 1. The correlation between transverse momentum and particle multiplicity is also investigated by studying the evolution of the spectra with event multiplicity. The results are compared with calculations from PYTHIA and EPOS Monte Carlo generators.
