在微扰理论中，重轻轴向矢流的时间分量被构造为1/M阶，其中M是重夸克质量，适用于B和D介子的格子模拟。O(A)-改进的三叶草作用量用于无质量轻夸克，其中a为晶格间距，重夸克的传播用非相对论晶格作用量来描述。{版权所有}{ital1998}{italthe American Physitive Society}
The temporal component of the heavy-light axial vector current is constructed to one-loop order in perturbation theory and to order 1/M, where M is the heavy quark mass, in terms of operators suitable for use in lattice simulations of B and D mesons. The O(a)-improved clover action is used for the massless light quark, where a is the lattice spacing, and propagation of the heavy quark is described by a nonrelativistic lattice action. {copyright} {ital 1998} {ital The American Physical Society}
