核束缚能效应对夸克分布的影响
The Effect of Nuclear Binding Energy on the Quark Distribution
【摘要】 根据核Drell-Yan过程的高能强子h同原子核A碰撞和高能轻子l同原子核A深度非弹性碰撞的实验数据,再考虑核子束缚能效应,计算并确定了价夸克分布函数RVA(xt)和海夸克分布核效应函数RSA(xt),深化了对原子核内夸克分布受核效应影响的认识.
【Abstract】 According to the experiment data of nuclear Drell-Yan process and the nuclear binding energy effect,the variety of nuclear effect functions of valence quark and sea quark distributions is discussed.Therefore,the knowledge of the influence of the nuclear effect on the quark distributions is deepened.
