The principle of maximum conformality (PMC) provides a convenient way for setting the optimal renormalization scales for high-energy processes, which can eliminate the conventional renormalization scale error via an order-by-order manner. At present, we make a detailed PMC analysis on the Higgs decay H ? ?? up to three-loop QCD corrections. As an important point of deriving reliable PMC estimation, it is noted that only those {?i}-terms that rightly determine the running behavior of coupling… Expand
