论文摘要
我们提出了一个可以简单地在晶格上实施的重新规范化方案。它由有限价夸克质量计算的两点和三点函数的时间矩组成。确认该方案可以在双线性操作员的连续性极限下使用另一个重新归一化的方案产生一致的结果。我们将类似的重新归一化方案应用于出现在弱有效的哈密顿量中的四个特里米昂操作员的非扰动重新归一化。
We propose a renormalization scheme that can be simply implemented on the lattice. It consists of the temporal moments of two-point and three-point functions calculated with finite valence quark mass. The scheme is confirmed to yield a consistent result with another renormalization scheme in the continuum limit for the bilinear operators. We apply a similar renormalization scheme for the non-perturbative renormalization of four-fermion operators appearing in the weak effective Hamiltonian.
