Lattice QCD calculation of weak decay matrix elements

这个项目将包括几项计算，旨在测试标准模型对夸克如何改变其味道的描述。包含上、下、奇夸克和粲夸克效应的现实规范场构型将形成计算相关函数的综合体。非相对论性和高度改进的交错夸克作用将用于计算中性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.
