论文摘要
我们使用IMOM（插值动量）方案计算夸克质量和波函数的重量法化因子。该框架是罗马 - 南汉普顿非氮差异法，但是夸克双线性中的动量转移不仅限于零或对称点。我们研究了该动量转移的不同值以及两种不同类型的投影仪的规模依赖性，红外污染和格子伪像。对于数值模拟，我们使用RBC-UKQCD协作生成的数据，$ n_f = 2+1 $ tomain-wall fermions的口味，以及$ 1.79 $和$ 2.38 $ gev的逆晶格间距。
We compute the renormalisation factors of the quark mass and wave function using IMOM (Interpolating MOMenta) schemes. The framework is the Rome-Southampton non-renormalisation method, but the momentum transfer in the quark bilinears is not restricted to zero or to the symmetric point. We study the scale dependence, infrared contamination and lattice artefacts for different values of this momentum transfer and for two different kinds of projectors. For the numerical simulations, we use data generated by the RBC-UKQCD collaborations, with $N_f = 2+1$ flavours of Domain-Wall fermions, and inverse lattice spacing of $1.79 $ and $2.38$ GeV.
