Photoproduction of High-p_T Kaon and Pion in pp and PbPb Collisions

Department of Physics, Yunnan University, Kunming 650091, China

摘要: 基于微扰量子色动力学(pQCD)，计算了考虑核遮蔽效应和喷注淬火效应的pp 和PbPb 碰撞中大横动量K和π的光生过程的产额。在光生过程中可以看到K⁺/π⁺ 的增强。数值计算结果表明，所考虑的光生过程对K和产生是一个很好的修正。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.
