通过次-次-首阶QCD构造了电流-电流算符的梯度流形式的有效电弱哈密顿量。结果是两个常见的选择的运营商的基础。这铺平了道路的一致匹配的扰动评估威尔逊系数和非微扰矩阵元素评估晶格模拟。
The effective electroweak Hamiltonian in the gradient-flow formalism is constructed for the current-current operators through next-to-next-to-leading order QCD. The results are presented for two common choices of the operator basis. This paves the way for a consistent matching of perturbatively evaluated Wilson coefficients and non-perturbative matrix elements evaluated by lattice simulations.
