Updated scalar sector constraints in the Higgs triplet model

Das, Dipankar LU and Santamaria, Arcadi (2016) In Physical Review D 94(1).
Abstract

We show that in the Higgs triplet model, after the Higgs discovery, the mixing angle in the CP-even sector can be strongly constrained from unitarity. We also discuss how large quantum effects in h→γγ may arise in a Standard-Model-like scenario and a certain part of the parameter space can be ruled out from the diphoton signal strength. Using T-parameter and diphoton signal strength measurements, we update the bounds on the nonstandard scalar masses.
