Signature of charged to neutral Higgs boson decay at the LHC in SUSY models

We study the signature of H± decay into h0W 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± decay into (h0,A0)W over a significant domain of parameter space.
