扭曲质量夸克的$N_f = 2+1+1$味:微扰理论树水平上的截止效应

$N_f = 2+1+1$ flavours of twisted mass quarks: cut-off effects at tree-level of perturbation theory

E. V. Luschevskaya, Krzysztof Cichy

摘要:

本文用格点量子色动力学的扭曲质量公式计算了K和D介子在三能级微扰理论下的截止效应。在时间-动量坐标系中进行了分析计算。截断效应的相对大小进行了比较的π介子,K介子和D介子的质量。此外,考虑了最大扭转条件的不同实现方式,并分析了相应的截止效应。

英文摘要:

We present a calculation of cut-off effects at tree-level of perturbation theory for the K and D mesons using the twisted mass formulation of lattice QCD. The analytical calculations are performed in the time-momentum frame. The relative sizes of cut-off effects are compared for the pion, the kaon and the D meson masses. In addition, different realizations of maximal twist condition are considered and the corresponding cut-off effects are analyzed.
