3-热规范理论的环规耦合

3-loop gauge coupling for hot gauge theories

York Schroder

摘要:

本讲座简要回顾了在降维有效场论的框架下,热QCD耦合常数的确定,特别是其胶子部分。有趣的是,高阶算子超出了通常的super-renormalizable截断的有效理论需要考虑匹配参数时,在三个循环。

英文摘要:

This talk offers a brief review of the determination of coupling constants in the framework of dimensionally reduced effective field theories for thermal QCD, specializing on its gluonic sector. Interestingly, higher-order operators that go beyond the usual super-renormalizable truncation of the effective theory need to be considered when matching parameters at three loops.
