Abstract

In the NMSSM, because of introducing a complex singlet superfield, the lightest CP-odd Higgs boson, a 1, can be a singlet-like state with a tiny doublet component in large regions of parameter space. In this paper, we examine the discovery potential of a 1 produced in association with a bottom–antibottom pair at the LHC through ? + ? ? and ?? decay modes. It is shown that an a 1 with mass ?M Z can be extracted from the SM backgrounds by using the ? + ? ? decay channel, a possibility precluded to the MSSM. In contrast, the ?? decay mode is overwhelmed by backgrounds despite the fact that the branching ratio of this mode can reach unity when a 1 is a pure singlet.
