Renormalization-Group Improved Higgs to Two Gluons Decay Rate

Abstract

We investigate the renormalization-group scheme and scale dependence of the H→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. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
