Multiplicity dependence of pi, K, and p production in pp collisions at root s=13 TeV
Original language description
This paper presents the measurements of pi(+/-), K-+/-, p and (p) over bar transverse momentum (p(T)) spectra as a function of charged-particle multiplicity density in proton-proton (pp) collisions at root s = 13 TeV with the ALICE detector at the LHC. Such study allows us to isolate the center-ofmass energy dependence of light-flavour particle production. The measurements reported here cover a pT range from 0.1 to 20 GeV/c and are done in the rapidity interval | y| < 0.5. The p(T)-differential particle ratios exhibit an evolution with multiplicity, similar to that observed in pp collisions at v s = 7 TeV, which is qualitatively described by some of the hydrodynamical and pQCD-inspired models discussed in this paper. Furthermore, the pT-integrated hadron-to-pion yield ratios measured in pp collisions at two different center-of-mass energies are consistent when compared at similar multiplicities. This also extends to strange and multi-strange hadrons, suggesting that, at LHC energies, particle hadrochemistry scales with particle multiplicity the same way under different collision energies and colliding systems.
