Jl. Diazcruz et al., RADIATIVE DECAYS OF HIGGS BOSONS IN MINIMAL EXTENSIONS OF THE STANDARD MODEL, Revista Mexicana de Fisica, 39(4), 1993, pp. 501-512
The radiative decay modes H --> gammagamma, gammaZ have been found to
be viable at SSC/LHC for detection of an intermediate mass range Higgs
boson expected in the standard model (SM). A precise measurement of t
he decay widths of these modes may be used to distinguish among theori
es beyond the SM. We present results obtained for the respective decay
widths in minimal extensions of the SM: left-right symmetric models w
ith a minimal Higgs potential, the minimal supersymmetric standard mod
el, and SU(2) x U(1) invariant Lagrangians in which any new physics ap
pears as nonrenormalizable, effective interactions. We conclude that o
nly in the last case the SM decay widths for these radiative modes may
be enhanced.
