Abstract

By taking into account the effects of shadowing and jet quenching, the production of high-pT kaon and pion originating from photoproduction processes in pp and PbPb collisions is calculated based on perturbative quantum chromodynamics(pQCD). The enhancement of K⁺/π⁺is found in photoproduction processes. The numerical results indicate that the photoproduction processes considering in our calculation are a good modification for kaon and pion production.
