The Z+photon and diphoton decays of the Higgs boson as a joint probe of low energy SUSY models at LHC

Abstract

In light of recent remarkable progress in Higgs search at the LHC, we study the rare decay process $h\to Z\gamma$ and show its correlation with the decay $h\to \gamma \gamma$ in low energy SUSY models such as CMSSM, MSSM, NMSSM and nMSSM. Under various experimental constraints, we scan the parameter space of each model, and present in the allowed parameter space the SUSY predictions on the $Z\gamma$ and $\gamma \gamma$ signal rates in the Higgs production at the LHC and future e+e- linear colliders. We have following observations: (i) Compared with the SM prediction, the $Z\gamma$ and $\gamma \gamma$ signal rates in the CMSSM are both slightly suppressed; (ii) In the MSSM, both the $Z\gamma$ and $\gamma \gamma$ rates can be either enhanced or suppressed, and in optimal case, the enhancement factors can reach 1.2 and 2 respectively; (iii) In the NMSSM, the $Z\gamma$ and $\gamma \gamma$ signal rates normalized by their SM predictions are strongly correlated, and vary from 0.2 to 2; (iv) In the nMSSM, the $Z\gamma$ and $\gamma \gamma$ rates are greatly reduced. Since the correlation behavior between the Zγsignal and the γγsignal is so model-dependent, it may be used to distinguish the models in future experiments.
