Very Light CP-odd Higgs bosons of the NMSSM at the LHC in 4b-quark final states
Abstract
We study the detectability of the lightest CP-odd Higgs boson of the NMSSM, a1, at the LHC through its production in association with a bottom-quark pair followed by the a1 b b decay. It is shown that, for large β and very high luminosity of the LHC, there exist regions of the NMSSM parameter space that can be exploited to detect the a1 through this channel. This signature is a characteristic feature of the NMSSM in comparison to the MSSM, as a1 masses involved are well below those allowed in the MSSM for the corresponding CP-odd Higgs state.
