2HDM-II-BSM

Asked by Basit Ali on 2021-02-07

Hello, I am working on 2HDM-II-BSM.

I am finding results for Bosonic Decays for charged Higgs.
But it is allowed by T-parameter. How these decays can be allowed?

I am calculating BR ( H- -> W-, H3).

and MH3=100 GeV as I have considered. But still the decay H- -> tb- is dominant. But it shouldn't.

First of all, I have no idea what is  2HDM-II-BSMmodel and where did you
get it.
I do not have it, so I can not check what you are talking about.

What is the problem?
As soon as m(H-) > m(W-)+m(H3) this decay is allowed

Why   H- -> tb-decay should not be dominant?

I do not see any grounds for your statement.
