LHC Signals of the Next-to-Lightest Scalar Higgs State of the NMSSM in the 4 τ Decay Channel

We study the and decay channels of the next-to-lightest CP-even Higgs boson of the NMSSM at the LHC, where the is produced in gluon fusion. It is found that while the discovery is impossible through the latter channel, the former one in the final state is a promising channel to discover the with masses up to around 250 GeV at the LHC. Such a discovery of the is mostly accompanied with a light , which is a clear evidence for distinguishing the NMSSM from the MSSM since such a light is impossible in the MSSM.
