摘要 利用扭度-4修正后的Dokshitzer-Gribov-Lipatov-Altarelli-Parisi(DGLAP)方程,结合HERMES的实验数据,计算出了领头阶情况下极化结构函数g_1以及不对称性A_1,讨论了扭度-4对核子自旋结构函数的影响. This paper calculated the proton and neutron spin structure function g1 and the asymmetry A1 with modified DGLAP equations which considered twist-4 effects. With the HERMES experiment data, we discussed twist-4 effect in polarized structure functions.
