摘要
提出了改进的双重Q2 重标度模型 ,在保持核动量守恒的条件下 ,用唯象的方法找到了一套重标度参数公式 ,建立了重标度参数 ξv,ξs 及 ξg 与原子核平均结合能之间的联系 .利用该模型所得到的束缚核子内部分子分布函数 ,对核DIS过程 ,核Drell Yan过程和J
In this paper we present an improved double Q(2) rescaling model. Based on this condition of the nuclear momentum conservation,we have found a Q(2) rescaling parameters' formula of the model,where we have established the connection between the Q(2) rescaling parameter xi (i)(i = v,s,g) and the mean binding energy in nucleus. By using this model,we coned explain the experimental data of the EMC effect in the whole x region,the nuclear Drell-Yan process and J/Psi photoproduction process.
