HQET重整化群中的旁观者效应改进了$\mathcal{O}(1/m^3)$上具有领先对数精度的拉格朗日量：自旋相关情况
Spectator effects in the HQET renormalization group improved Lagrangian at $\mathcal{O}(1/m^3)$ with leading logarithmic accuracy: Spin-dependent case
摘要：
本文在与${\cal O}(1/m^3)$自旋相关的重夸克有效理论拉格朗日算符相关的重整化群改进的Wilson系数中考虑了无质量旁观夸克引起的效应。计算是在库仑规下进行的，具有较高的对数精度。结果以该精度将拉格朗日量完成为$\mathcal{O}(1/m^3)$。
英文摘要：
The present paper incorporates the effects induced by massless spectator quarks in the renormalization group improved Wilson coefficients associated to the ${\cal O}(1/m^3)$ spin-dependent heavy quark effective theory Lagrangian operators. The computation is carried out in Coulomb gauge with leading logarithmic precision. The result completes the Lagrangian to $\mathcal{O}(1/m^3)$ with that accuracy.
