[Abstract]:The standard model (SM) of particle physics can unify the electromagnetic interaction, strong and weak interaction in nature. In the past few decades, a large number of accurate experiments have successfully verified the standard model theory. With the discovery of 125GeV's Higgs boson by the large Hadron Collider, the last prediction of particles in the standard model has been confirmed. There is no doubt that the standard model theory is one of the most perfect theories in particle physics. However, the standard model is not an ultimate theory, and there are still many problems in particle physics that can not be solved in the framework of the standard model theory. For example, the standard model has a big problem in the fine regulation of Higgs quality; the standard model can not explain why neutrinos have mass; in addition, the standard model can not provide dark matter candidates. The standard model can be regarded as a successful low energy efficiency theory, and there may be new physical existence at higher energy standards. The low energy supersymmetric standard model is the supersymmetric extension of the standard model. It can well explain the specification level problem of the standard model (SM), successfully realize the great unity of the three kinds of specification coupling, and provide the suitable dark matter candidate. Explain the baryons asymmetry in the universe, so many physicists think it is one of the best candidates for new physics on the TeV scale. However, the lack of new supersymmetric particle signals seems to indicate that the low energy supersymmetry theory is not in harmony with LHC experiments, and LHC data have strict limitations on some simple supersymmetric theoretical models (such as CMSSM, etc.). In this paper, the subminimum supersymmetric standard model (NMSSM), is implemented in the generalized Mirage transfer mechanism and its phenomena are studied. This paper mainly includes the following aspects: (1) abnormal transmission needs an additional mechanism to deal with-B problem. The working framework of the subminimum supersymmetric standard model (NMSSM) can naturally solve the B problem. In addition, NMSSM can easily explain the Higgs particle mass of 125GeV by adding additional tree contributions. Through a generalized hybrid modulus-anomaly transfer mechanism, we generate such a subminimum supersymmetric (NMSSM) soft breaking spectral structure. (2) in the previous work of the research group, The supersymmetric soft breakdown spectral structure and low energy phenomena when the medium field-material field interaction is introduced into the abnormal transfer mechanism of deflection are discussed in detail. It is found that the introduction of media field into the deflected Mirage transfer mechanism can make an additional contribution to the supersymmetric soft breaking spectrum. It is found that the contribution of the mixed gauge-modulus interference term may be given by introducing the media field. By introducing the media field into the Mirage transfer mechanism, the modular weight of the material field can be selected more freely. (3) in this paper, the analytical expressions of soft breaking mass and trilinear coupling term in the generalized mirage transfer are discussed. By introducing the appropriate medium field and its interaction form, the soft breaking parameters of NMSSM are given, and the dark matter limitation, the abnormal magnetic moment of muon and the fine adjustment degree of BG theory are also discussed in this paper. The related numerical analysis is also given in this paper.
