Abstract
In this paper we study the particle production at high transverse momentum in both and Pb-Pb collisions at LHC energies. The characterization of the spectra is done using a power-law function and the resulting power-law exponent is studied as a function of for minimum-bias collisions at different . The functional form of as a function of exhibits an approximate universal behavior. pythia 8.212 reproduces the scaling properties and therefore, it is used to study the multiplicity-dependent particle production. Going from low to high multiplicities, the power-law exponent decreases. A similar behavior is also observed in heavy-ion collisions when one studies the centrality-dependent particle production. The interpretation of heavy-ion results requires the quantification of the impact of this correlation (multiplicity and high on jet-quenching observables.
