Abstract

We present a detailed analysis of the Higgs boson decays and in the SSM, with denoting one of the mesons (). Using the effective Lagrangian method, we calculate the effective constants (CP-even) and (CP-odd) for the vertex , which are corrected by the new particle loop diagrams. Numerically, the ratio is between 1.02 and 1.35. For the vector mesons and , the ratios are mainly distributed in the range of (1.01–1.45). When represents , the ratio is mostly located in the range of (1.002–1.30). The aim of this work is to provide a reference for probing the SSM model via the Higgs decays and .
