Differential yields of light flavored charged hadrons in [Formula: see text] collision at 0.9 TeV in the transverse momentum [Formula: see text] ranging from 0.1–2.5 GeV/c with pseudorapidity [Formula: see text] are presented here. The spectra obtained by Monte Carlo simulations with event generators — EPOS 1.99, EPOS-LHC, QGSJETII-04 and Sibyll2.3c — are compared with the ALICE measurements. For [Formula: see text] mesons, EPOS1.99, EPOS-LHC and QGSJETII-04 described the ALICE measurement very well almost in the entire [Formula: see text] range except QGSJETII-04 which underpredicts with [Formula: see text] below 0.4 GeV/c. The Sibyll2.3c model slightly overpredicts for [Formula: see text] GeV/c and underpredicts afterwards. For [Formula: see text] mesons, all models describe the experimental data qualitatively, except at high [Formula: see text], where the models slightly underpredict. The EPOS-LHC and QGSJETII-04 models, at low [Formula: see text], describe the distribution of the experimental measurements very well in both cases of protons and anti-protons, whereas the former underpredicts and the latter overpredicts at higher [Formula: see text]. The EPOS1.99 overpredicts at low [Formula: see text] below 1 GeV/c, whereas it reproduces the results well above it. Sibyll2.3c overpredicts the distribution over the entire range of [Formula: see text]. Models described the average transverse momentum [Formula: see text] of these hadron species as a function of their mass, showing small rise in the average [Formula: see text] with the mass of the particles. The same has been observed by the STAR collaboration with measurements in [Formula: see text] reactions at [Formula: see text] = 200 GeV and also in [Formula: see text] collisions at [Formula: see text] = 900 GeV.

The semiempirical formulation of Ghosh et al. for the energy dependence of multiplicity in hadronic collisions has been applied to account for the experimental multiplicity data of π±p and K±p collisions. A remarkable agreement has been found over the entire energy range.
