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.

这个项目将包括几个计算，旨在测试夸克如何改变它们的味道的标准模型描述。包含上夸克、下夸克、奇异夸克和粲夸克效应的现实规范场组态将形成计算关联函数的系综。非相对论性和高度改进的交错夸克作用量将被用来计算矩阵元，这些矩阵元是为中性B介子系统的混合和B介子的衰变提供理论预测所必需的。
