推广x重新标度模型重标度参数公式与轻子-核DIS过程的核效应

The x rescaling parameter′ formula of the extended x rescaling model and the nuclear effect 1-A DIS process

与原子核的平均结合能相联系 ,给出了部分子的推广x重新标度模型的重标度参数公式 .利用该公式给出的重标度参数值 ,计算了铝核、钙核、铅核分别与碳核DIS过程的平均结构函数之比 ,结果表明理论计算与实验数据符合较好 .

In this paper we present an x rescaling paramenters' formula for partons in the extended x rescaling model, where we have established the connection between the rescaling parameter and the mean binding energy. Using x rescaling parameters obtained by the x rescaling parameters' formula, We calculate the average nucleon structure function ratio of DIS process in l-A Al, Ca, Pb) collision to l-C collision respectively. The result is in good agreement with experimental data.
