Signature of Charged to Neutral Higgs Boson Decay at the LHC in SUSY Models

TL;DR

This paper investigates the potential signatures of charged Higgs boson decays into neutral Higgs and W bosons at the LHC within SUSY models, highlighting the viability in NMSSM but limited prospects in MSSM.

Contribution

It demonstrates that singlet extensions like NMSSM can produce distinctive decay signatures of charged Higgs bosons, unlike the MSSM.

Findings

Marginal viability of $H^ o$ decay in MSSM.

Spectacular signatures possible in NMSSM.

Significant parameter space for $H^ o$ decay in NMSSM.

Abstract

We study the signature of $H^\pm$ decay into $h^0W$ at the LHC in SUSY models. It has only marginal viability in the MSSM. But in the singlet extensions like the NMSSM one can have a spectacular signature for $H^\pm$ decay into $(h^0,A^0)W$ over a significant domain of parameter space.
