摘要

本报告简要回顾了在降维有效场理论框架下的耦合常数的确定，特别是在其胶子扇区。有趣的是，当在三个循环中匹配参数时，需要考虑超出通常的有效理论的超重整化截断的高阶算子。

3-loop coupling for hot gauge theory

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.
