中文摘要：
计算了相对论重离子碰撞中轻矢量介子(ρ,ω和φ)的光生过程。基于窄-宽近似,严格推导了相对论重离子碰撞中ρ,ω和φ半弹性和非弹性光生过程的遍举和单举横截面。从数值结果可以看出对于p-p碰撞,光生过程的贡献是不重要的,但是对于pT】2.5 GeV Au-Au碰撞和pT】3 GeV Pb-Pb碰撞,轻矢量介子光生过程的贡献是明显的。
英文摘要：
We calculate the photoproduction processes of light vector meson(ρ,ωand?) in heavy ion collisions. Based on the narrow-width approximation, we rigorously derive the exclusive and inclusive cross sections of ρ, ω and ? produced by the semielastic and inelastic photoproduction processes in relativistic heavy ion collisions. The numerical results indicate that contribution of photoproduction processes of light vector meson is not prominent for p-p collisions, but the contribution becomes evident for pT>2.5 GeV in Au-Au collisions and pT>3 GeV in Pb-Pb collisions.
