Analysisofthestandardmodelofparticlephysicsandbeyondusingchiralfermions

为了在粒子物理标准模型（SM）中对Cabibbo-Kobayashi-Maskawa（CKM）理论进行精度检验，构建或测试了一系列晶格量子计算的新技术，这是当前粒子物理的汇编。这些产生的主要系统误差的减少1/5 s夸克的质量,平均ud夸克的质量,在SM的基本参数,使人们有可能确定π,K介子衰变常数和中性K介子混合参数精度高,并已用于B介子衰变常数的精密测量和混合参数,以及质子衰变矩阵元素的计算任务所需的物理超出SM。

A series of new techniques in thelattice QCDcomputationare lattice constructed or tested, aiming a precision test of Cabibbo-Kobayashi-Maskawa(CKM) theory in the standard model(SM) of particle physics, which is the current compilation of the particle physics. These yielded the reduction of the main systematic error to 1/5 on the s-quark mass, average ud quark mass, which are the fundamental parameters in SM, made it possible to determine the pi, K meson decay constant and neutral K meson mixing parameter to a high precision, and have been used to a precision measurements of the B meson decay constants and mixing parameters, as well as to the calculation of the proton decay matrix elements needed for the quest of the physics beyond SM.
