Abstract
The multiplicity dependence of the pseudorapidity density of
charged particles in proton–proton (pp) collisions at centre-of-mass
energies s=5.02, 7 and 13 TeV measured by ALICE is reported. The
analysis relies on track segments measured in the midrapidity range (|
η| < 1.5). Results are presented for inelastic events having at least
one charged particle produced in the pseudorapidity interval | η| <
1. The multiplicity dependence of the pseudorapidity density of charged
particles is measured with mid- and forward rapidity multiplicity
estimators, the latter being less affected by autocorrelations. A
detailed comparison with predictions from the PYTHIA 8 and EPOS LHC
event generators... (More)
