Lattice QCD calculation of weak decay matrix elements

这个项目将由几项计算组成，旨在测试夸克如何改变其味道的标准模型描述。包含上夸克、下夸克、奇异夸克和魅力夸克效应的真实规范场组态将形成系综，在系综内计算关联函数。非相对论和高度改进的交错夸克作用将被用来计算给出中性B介子系统混合和B介子衰变的理论预测所需的矩阵元素。

This project will consist of several calculations aiming to test the Standard Model description of how quarks change their flavour. Realistic gauge field configurations containing the effects of up, down, strange and charm quarks will form the ensembles within which correlations functions are computed. Nonrelativistic and highly improved staggered quark actions will be used to calculate matrix elements needed to give theoretical predictions for mixing in neutral B meson systems, and the decays of B mesons.
