The pseudorapidity (eta) and transverse-momentum (p(T)) distributions of charged particles produced in proton-proton collisions are measured at the centre-of-mass energy root s = 13 TeV. The pseudorapidity distribution in vertical bar eta vertical bar < 1.8 is reported for inelastic events and for events with at least one charged particle in vertical bar eta vertical bar < 1. The pseudorapidity density of charged particles produced in the pseudorapidity region vertical bar eta vertical bar < 0.5 is 5.31 +/- 0.18 and 6.46 +/- 0.19 for the two event classes, respectively. The transverse-momentum distribution of charged particles is measured in the range 0.15 < p(T) < 20 GeV/c and vertical bar eta vertical bar < 0.8 for events with at least one charged particle in vertical bar eta vertical bar < 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.
