摘要
The discovery of Higgs is the last piece of standard model in particle physics.In December 2011,the Large Hadron Collider(LHC) have reported that they found some excess of signal in searching SM-like Higgs at 124GeV-126GeV.Motivated by the data,we use UMSSM model to search the SM-like Higgs. In this article,I briefly introduce the UMSSM model.Then I use this model to derive the mass of CP-even Higgs and then scan parameter space for the SM-like Higgs in the two ranges: (i)130 GeV < mh(SM−like) < 141 GeV (ii)120 GeV < mh(SM−like) < 130 GeV. We also investigate the branching ratio of Higgs to b ar{b} , WW^* ,and chi chi.
