摘要
以微扰QCD方法计算了质子与C、Be、Al、Cu和Pb核散射截面的横动量分布、快度分布及末态介子产额.在800GeV高能区对原子核的EMC效应的影响进行了比较和讨论.其横动量分布截面的理论结果与目前的实验基本符合.
According to the perturbative QCD method, we have calculated the P_⊥ distributive cross sections, the Y distributive cross sections of the large P jets and the final state meson productivities in 800 GeV/c Proton-Nucleus (Be, C, Al, Cu and Pb) collisions. The A dependence of the cross section at a given P_⊥ was discussed by the EMC effect. The dσ/dP(?) differential cross sections vs. P_⊥ for various PA collisions are consistent with the new data.
