Wu and Xu-Chang Zheng and Gu Chen and Jian-Ming Shen}, journal={Journal of Physics G}, year={2013}, volume={41}, pages={075010} } 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.
