Renormalization-Group Improved Higgs to Two Gluons Decay Rate
摘要
We investigate the renormalization-group scheme and scale dependence of the \(H \rightarrow gg\) decay width in renormalization-group summed perturbation theory. Moreover, the higher order behaviour of the decay width is also studied using asymptotic Padé and asymptotic Padé-Borel approximant formalisms. The predictions of the asymptotic Padé-Borel formalism show a good agreement with that of the asymptotic Padé formalism.
