核内夸克分布与轻子-核DIS过程中的核效应
Quark Distributions in Nuclei and Nuclear Effect of l-A DIS process
在改进的核密度模型基础之上,通过拟合大量的深度非弹性散射实验数据,得到了推广的夸克分布参数公式,能够很好地解释深度非弹性散射实验中0.0010≤x≤0.9500 区域内A≥3 的核效应的实验数据,推广的夸克分布参数公式的合理性得到了检验,加深了夸克分布受核环境影响的认识.
Extended quark distribution parameter formulas are presented according to fitting abundant experimental data in l-A DIS process on the basis of improved nuclear density model. The experimental data in l-A DIS process of A≥3 within the region 0.0010≤x≤0.9500 are quite satisfactorily explained by using the extended formulas. The formulas’ reasonableness is tested and the knowledge of the influence of the nuclear matter on quark distribution is deepened.
