Applying distillation approximation to heavy-light quark decays

Michael正在通过对网格(RBC-UKQCD使用的晶格QCD代码)进行加法来实现蒸馏，这是介子场结构中的一种数值近似，因此n点关联函数通过仅使用狄拉克矩阵逆的最重要的特征向量计算来提供速度和收敛改进。其目的是将蒸馏应用于重轻夸克衰变，以便在信噪比损失(目前发生的情况)之前，在模拟的早期获得信号。

Michael is beginning his research by making an addition to Grid (the Lattice QCD code used by RBC-UKQCD) to implement distillation, which is a numeric approximation in the construction of meson fields and hence n-point correlation functions which delivers speed and convergence improvements by calculating with only the most significant eigenvectors of the inverse of the Dirac matrix. The intention is to apply distillation to heavy-light quark decays, in order to obtain a signal earlier in the simulation, prior to loss of signal to noise (as currently occurs).
