论文摘要
我们没有经常使用的非相关量子染色体动力学（NRQCD）中经常使用的褶皱 - 瓦森 - 塔尼（FWT）转换，而是在相对论和非权益主义的壳旋转纺纱机之间进行了更一般的关系，以重新计算Quark-Quark-Quark-Quark-Quark-Quark-gluonthers for Hupeed Quarks。与以前使用FWT的结果相比，NRQCD Lagrangian中的重新计算系数以$ 1/m^3 $的订单不同，订单为$ 1/m^4 $和$ 1/m^5 $，其中$ m $是重型夸克质量。
Instead of the often used Foldy-Wouthuysen-Tani (FWT) transformation in non-relativistic quantum chromodynamics (NRQCD), we take a more general relation between the relativistic and non-relativistic on-shell spinors to recalculate the quark-quark-gluon vertex for heavy quarks. In comparison with the previous result using FWT, the recalculated coefficients in the NRQCD Lagrangian are different at order $1/m^3$ and new at order $1/m^4$ and $1/m^5$, where $m$ is the heavy quark mass.
