In this talk, we derive new one-loop formulas for Higgs $\rightarrow V V^{*}$ with $V, V^{*} = \gamma (\text{photon}), Z$. Analytic results are expressed in terms of generalized hypergeometric functions which are valid in general space-time dimension. We also confirmed previous results in $d = 4$. \\ References: 1.
