• This paper presents the measurements of π ± , K ± , p and p ¯ transverse momentum ( p T ) spectra as a function of charged-particle multiplicity density in proton–proton (pp) collisions at s = 13 TeV with the ALICE detector at the LHC. Such study allows us to isolate the center-of-mass energy dependence of light-flavour particle production. The measurements reported here cover a p T 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 s = 7 TeV , which is qualitatively described by some of the hydrodynamical and pQCD-inspired models discussed in this paper. Furthermore, the p T -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.
