Non-standard charged Higgs decay at the LHC in Next-to-Minimal Supersymmetric Standard Model

Understand

We consider next-to-minimal supersymmetric standard model (NMSSM) which has a gauge singlet superfield.

• In the scale invariant superpotential we do not have the mass terms and the whole Lagrangian has an additional $Z_3$ symmetry.
• This model can have light scalar and/or pseudoscalar allowed by the recent data from LHC and the old data from LEP.
• We investigate the situation where a relatively light charged Higgs can decay to such singlet-like pseudoscalar and a $W^\pm$ boson giving rise to final state containing $\tau$ and/or $b$-jets and lepton(s).
