论文摘要
我们通过分析将三循环校正计算到在最小化（$ {\ rm \ rm \ overline {ms}} $）中定义的重量化夸克质量之间的关系与正则化invariant invariant对称对称动量 - 补充（$ {$ {\ rm rm ri/smom} $）。我们的结果在Landau仪表中是有效的，可以用来减少$ {\ rm \ overline {ms}} $ quark Masses的晶格确定的不确定性。
We analytically compute the three-loop corrections to the relation between the renormalized quark masses defined in the minimal-subtraction (${\rm \overline{MS}}$) and the regularization-invariant symmetric momentum-subtraction (${\rm RI/SMOM}$) schemes. Our result is valid in the Landau gauge and can be used to reduce the uncertainty in a lattice determination of the ${\rm \overline{MS}}$ quark masses.
