Concerning the searches for Higgs bosons

Abstract

The great successes achieved by the Standard Model(SM) lead us to believe the existence of the Higgs particle. On the other hand, there are many evidences indicate that some unknown dark matter particle must exist in our universe. To identify the Higgs boson as the dark matter particle is difficult in the present SM, the challenge is: the Higgs particle is unstable while the dark matter particle is stable. A solution of this problem is proposed in this paper. We will describe a model in which almost all the predictions made by the present SM remain unchanged but leave two neutral stable Higgs particles, which may be the dark matter particle. Some possible experimental tests of Higgs particle are also suggested in this paper.
