Light Pseudoscalar Higgs boson in Neutralino Decays in the Next-to-Minimal Supersymmetric Standard Model

Abstract

We point out another important production channel of a light pseudoscalar Higgs boson $a_1$ via the decays of neutralinos, including ${\tilde{\chi }}_{2,3}^0\to {\tilde{\chi }}_1^0{a}_1$, in the framework of the NMSSM. We scan the whole parameter space using the most up-to-date version of NMHDECAY and search for regions where $B({\tilde{\chi }}_{2,3}^0\to {\tilde{\chi }}_1^0{a}_1)>0.5$. If the gluino and squarks are light enough for copious production of SUSY events at the LHC, there would be numerous number of ${\tilde{\chi }}_{2,3}^0$ in subsequent decays of gluinos and squarks. Therefore, the production rates of $a_1$ via neutralino decays would be more important than $h\to a_1{a}_1$ and others. Potentially, the final state is filled with many $\tau$ leptons, which can be reconstructed at the mass of $a_1$. This is a clean, observable, and distinguishable signature for NMSSM.
