| 英文摘要 | In light of recent remarkable progress in Higgs search at the LHC, we study the rare decay process h -> Z gamma and show its correlation with the decay h -> 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 at the LHC can reach 1.1 and 2 respectively; (iii) In the NMSSM, the Z gamma and gamma gamma signal rates normalized by their SM predictions are strongly correlated, and at the LHC the rates vary from 0.2 to 2; (iv) In the nMSSM, the Z gamma and gamma gamma rates are both greatly reduced. Since the correlation behavior between the Z gamma signal and the gamma gamma signal is so model-dependent, it may be used to distinguish the models in future experiments. |
