Hypergeometric presentation for one-loop contributing to $H\to Z\gamma$

Abstract

In this paper, new analytic formulas for one-loop contributing to Higgs decay channel $H\to Z\gamma$ are presented in terms of hypergeometric functions. The calculations are performed by following the technique for tensor one-loop reduction developed in [A.~I.~Davydychev, Phys.\ Lett.\ B {\bf 263} (1991) 107]. For the first time, one-loop form factors for the decay process are shown which are valid at arbitrary space-time dimension $d$.
