标题： Effect of gluon-exchange pair-currents on the ratio G(E(P))/G(M(P))

摘要： 一胶子交换（OGE）对质子比值$\mu_p G_E^p/G_M^p$的影响在非相对论性组分夸克模型（CQM）中进行了研究，这是从$SU(6) \times O(3)$核子波函数出发，但考虑了相对论修正。 我们发现，OGE 对电流对于良好地再现比值$\mu_p G_E^p/G_M^p$是重要的。 在假设 OGE 对电流是违反标度定律的驱动机制的前提下，我们给出了中子比值$\mu_n G_E^n/G_M^n$的预测。 显示英文摘要

摘要： The effect of one-gluon-exchange (OGE) pair-currents on the ratio $\mu_p G_E^p/G_M^p$ for the proton is investigated within a nonrelativistic constituent quark model (CQM) starting from $SU(6) \times O(3)$ nucleon wave functions, but with relativistic corrections. We found that the OGE pair-currents are important to reproduce well the ratio $\mu_p G_E^p/G_M^p$. With the assumption that the OGE pair-currents are the driving mechanism for the violation of the scaling law we give a prediction for the ratio $\mu_n G_E^n/G_M^n$ of the neutron.
