Description
The loop-mediated higgs decays constrain the model parameter space
of the neutrino mass mechanism based on the fermionic quintuplet
in conjunction with the scalar quadruplet. The most significant increase to the higgs to diphoton decay width comes from a doubly charged scalar component, which should be the lightest component in the scalar quadruplet. There is an anti-correlation to the h --> Z gamma decay width, a mild suppression by a factor 0.9 -- 0.7 in the part of the parameter space where the h --> gamma gamma decay width is enhanced by a factor 1.25 -- 2.
