Abstract

In this paper we briefly review the LHC discovery potential of a light pseudoscalar Higgs boson of the NMSSM, $a_{1}$ , produced in the gluon fusion $g g \to a_{1}$ , bottom-quark fusion $b b ˉ \to a_{1}$ and bottom-gluon fusion $b g \to b a_{1}$ . We also review the LHC discovery potential of the next-to-lightest CP-even Higgs boson $h_{2}$ being the non-SM-like Higgs, decaying either into two light CP-odd Higgs bosons $a_{1} a_{1}$ or into a light $a_{1}$ and the $Z$ gauge boson through the gluon fusion $g g \to h_{2}$ in the 4 $τ$ final state. We find that the light $a_{1}$ can be detected at the LHC in a variety of production processes including the gluon fusion, bottom-quark fusion and bottom-gluon fusion. The latter two processes require high luminosity of the LHC and large values of tan $β$ . We also find that the LHC has the potential to discover the non-SM-like Higgs state, $h_{2}$ , decaying into a pair of light CP-odd Higgses $a_{1}$ 's, allowing to distinguish the NMSSM Higgs sector from the MSSM one as such a light $a_{1}$ is impossible in the latter scenario.
