论文摘要
我们讨论在BMHV方案中尺寸符号符号的手性磁场理论的背景下，如何使用代数重态化框架来始终如一地制定重量法化的组方程，其中最初在量子级别损坏的BRST对称性是通过有限反击恢复的。我们将其与更标准的乘法重量级化方法进行了比较，在这种情况下，应用程序将更加麻烦。使用两种程序进行了应用，并以无质量的手性右手QED模型进行比较，并评估β-功能和异常尺寸最多两层循环订单。
We discuss how renormalisation group equations can be consistently formulated using the algebraic renormalisation framework, in the context of a dimensionally-renormalised chiral field theory in the BMHV scheme, where the BRST symmetry, originally broken at the quantum level, is restored via finite counterterms. We compare it with the more standard multiplicative renormalisation approach, which application would be more cumbersome in this setting. Both procedures are applied and compared on the example of a massless chiral right-handed QED model, and beta-function and anomalous dimensions are evaluated up to two-loop orders.
