The Nuclear Effects on Valence Quark Distributions and Sea Quark Distributions 价夸克分布与海夸克分布的核效应
A method is presented to get nuclear effect functions R A v ( x t ) and R A x ( x t ) on valence quark distributions and sea quark distributions from the data of 1-A DIS process and nuclear Drell-Yan process. 提出了一个由1-A的深度非弹性散射和核Drel-Yan过程的实验数据得到价夸克分布和海夸克分布的核效应的函数RAV(xt)和RAs(xt)的方法。
In this paper, we separate sea quarks in bound nucleon into two parts : one part, which is affected by the nuclear binding effect together with valence quark, is called cloud sea quark; 把束缚核子内海夸克从物理上分为两部分:一部分是伴随价夸克受核束缚效应影响的云海夸克;
