矢量介子为主与小x区EMC效应

Vector Meson Dominate and Small x Region EMC Effect

本文利用矢量介子为主假设给出EMC和SLAC实验组在小x区的比值r的差别,讨论了当Q^2小时矢量介子对深度非弹性散射的贡献是不能忽略的,于是产生了EMC效应申的遮蔽效应。

The vector meson dominate hypothesis is used to explain the difference between EMC and SLAC data of γ in small x region.It is argued that when Q^2 becomes smaller the vector mesons' contribution to DIS can not be neglected,which cause the shadowing in the EMC effect.
