部分守恒轴矢量流及其应用
Partially conserved axial vector current and applications
摘要：
我们调查的影响，使用点分裂轴向矢量电流来自威尔逊像费米子行动。我们计算相应的重整化因子非微扰一个beta值。从这个非局部电流计算的轴向电荷GA被发现是更接近的物理值比计算与本地轴向矢量电流-计算在同一晶格上具有相同的动作。
英文摘要：
We investigate implications of the use of the point-split axial vector current derived from a Wilson like fermionic action. We compute the corresponding renormalization factor nonperturbatively for one beta value. The axial charge gA calculated from this nonlocal current is found to be nearer to the physical value than computed with the local axial vector current -- computed both on the same lattice with the same action.
