Abstract

In this piece of work, the nonstandard Higgs boson masses have been constrained by restrictions arising from Higgs diphoton decay width, stability, perturbativity, unitarity and electroweak T-parameter in the framework of the Higgs triplet model. As a matter of fact the loop induced Higgs decays will now obtain additional contributions from singly and doubly charged Higgs bosons. In simulations of pair production of $H^{++}$ it is assumed that the production channel $q\overline{q}\rightarrow \gamma^{*},Z^{*}\rightarrow H^{++}H^{--}$ is the only mechanism. Whereas there may be other channels of production of doubly charged Higgs bosons as for instance from the decay of singly charged Higgs bosons. The effect of this additional sources of production of the contributing non-standard charged particles to the loop induced Higgs decays has been studied in this paper.
