Original language description
We present a study of the inclusive charged-particle transverse momentum (p(T)) spectra as a function of charged-particle multiplicity density at mid-pseudorapidity, dNch/d., in pp collisions at root s = 5.02 and 13TeV covering the kinematic range vertical bar eta vertical bar < 0.8 and 0.15 < p(T) < 20GeV/c. The results are presented for events with at least one charged particle in vertical bar eta vertical bar < 1 (INEL> 0). The p(T) spectra are reported for two multiplicity estimators covering different pseudorapidity regions. The p(T) spectra normalized to that for INEL> 0 show little energy dependence. Moreover, the high-p(T) yields of charged particles increase faster than the charged-particle multiplicity density. The average p(T) as a function of multiplicity and transverse spherocity is reported for p(T) collisions at root s = 13TeV. For low- (high-) spherocity events, corresponding to jet-like (isotropic) events, the average pT is higher (smaller) than that measured in INEL> 0 pp collisions. Within uncertainties, the functional form of < p(T)> (N-ch) is not affected by the spherocity selection. While EPOSLHCgives a good description ofmany features of data, PYTHIA overestimates the average p(T) in jet-like events.
