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

Kingman Cheung, Tie-Jiun Hou

We point out another important production channel of a light pseudoscalar Higgs boson $a_1$ via the decays of neutralinos, including ${\tilde{\chi }}_{2,3}^0\to {\tilde{\chi }}_1^0{a}_1$…
