摘要 借助Glauber模型,利用拟合深度非弹性散射实验数据得到的束缚核子中的部分子分布函数,计算了核Drell-Yan过程微分截面比随运动学变量x1的变化,并与费米实验室E866组的实验结果进行比较,发现在考虑了能量损失效应后能解释大的x1区域理论值比实验值低的实验现象。 Based on the Glauber model, the nucleon structure functions by fitting the deep inelastic scattering experimental data are used to calculate the variation of differential cross section ratios to x, in nuclear Drell-Yan processes. The results are compared with those of Feimilab Experiment 866. It is found that the energy loss effect can be used to interpret the experimental data.
