摘要
利用改进的核密度模型和动量守恒条件,找到了核内胶子分布函数的核效应参数公式,其中利用了已经建立的核密度与原子核的平均结合能之间的联系.利用该模型所得到的核内胶子分布函数,对轻子打靶核的J/ψ光生过程的核效应给出了满意的解释,深化了核内胶子分布函数受核效应影响的认识.
Based on the improved nuclear density model and the Condition of the nuclear momentum conservation, we derived the formula of the nuclear effect parameter formula for the nuclear gluon distribution function, in which our established connection between the nuclear density and the mean binding energy in nucleus is used. By using the formula, we can well explain the experimental data of the J/ψ photoproduction in the 1-A process.
