General one-loop formulas for decay $$h\rightarrow Z\gamma $$ h → Z γ

Abstract

Radiative corrections to the decay h → Z γ are evaluated in the one-loop approximation. The unitary gauge is used. The analytic result is expressed in terms of the Passarino-Veltman functions. The calculations are applicable for the Standard Model as well for a wide class of its gauge extensions. In particular, the decay width of a charged Higgs boson H ± → W ± γ can be derived. The consistence of our formulas and several specific earlier results is shown. ening discussions and comments about divergences and counterterms.

Self-couplings of gauge bosons in 3-4-1 models

“…In addition,G 0 = A, Z 1 , Z 2 , Z 3 belong to the linear combinations of neutral gauge bosons. Then, theLagrangian (23) is written in a standard form as follows:…”

“…where W + ≡ W 12 is the SM charged gauge boson and X = {(12, 13), (12,14), (13,14), (13,23), (13,14), (23,24), (14,24), (14, 34), (24, 34)} Y = { (12,23), (12,24), (13, 34), (23, 34)}.…”

Effects of one-loop on-shell and off-shell decay H* → VV at future lepton colliders

“…While one-loop electroweak corrections to Higgs boson decay into γγ, Zγ, ZZ have been calculated in Refs. [31,32,33,34,36,37,38,39,40,41]. In this paper, we present one-loop on-shell and off-shell decays H → V V with V V = γγ, Zγ, ZZ.…”
