Improved Partou Evolution Model and Its Explanation to the EMC Effect and the Nuclear Drell-Yan Process

  • In this paper,we prove analytically that the parton evolution model can provide a physical basis to the double x-rescaling model. Then we describe the nuclear shadowing and antishadowing effect in the small x region using the modified Alteralli-Parisi equation to improve the parton evolution model.The unified description of the EMC effect,the nuclear shadowing effect,and antishadowing effect is given without introducing the nuclear shadowing factor.Finally,we explain the experimental data of the Drell-Yan process with the improved parton evolution model.

Abstract: In this paper,we prove analytically that the parton evolution model can provide a physical basis to the double x-rescaling model. Then we describe the nuclear shadowing and antishadowing effect in the small x region using the modified Alteralli-Parisi equation to improve the parton evolution model.The unified description of the EMC effect,the nuclear shadowing effect,and antishadowing effect is given without introducing the nuclear shadowing factor.Finally,we explain the experimental data of the Drell-Yan process with the improved parton evolution model.
