Particle Ratios at High p_T at LHC Energies

TL;DR

This paper investigates high transverse momentum hadron ratios at LHC energies using pQCD models, revealing that quark contributions primarily influence these ratios, with implications for jet energy loss and suppression patterns.

Contribution

It introduces a detailed analysis of hadron ratios at high p_T using fragmentation functions and highlights the dominant role of quark contributions over gluonic ones.

Findings

Hadron ratios at high p_T are mainly influenced by quark contributions.

Jet energy loss calculations reflect the dependence of hadron ratios on quark contributions.

Suppression patterns in PbPb collisions are characterized at LHC energies.

Abstract

Hadron production has been calculated in a pQCD improved parton model for pp, dA and heavy ion collisions. We applied KKP and AKK fragmentation functions. Our jet fragmentation study shows, that hadron ratios at high p_T depend on quark contribution mostly and less on the gluonic one. This finding can be seen in jet-energy loss calculations, also. We display the suppression pattern on different hadron ratios in PbPb collisions at LHC energies.
