Three-Particle Decays of the Higgs Bosons in the Minimal Supersymmetric Standard Model

The purpose of this paper is to present a complete and consistent list of the Feynman rules for the vertices of neutralinos and Higgs bosons in the Next-To-Minimal Supersymmetric Standard Model (NMSSM), which does not yet exist in the literature. The Feynman rules are derived from the full expression for the Lagrangian and the mass matrices of the neutralinos and Higgs bosons in the NMSSM. Some crucial differences between the vertex functions of the NMSSM and the Minimal Supersymmetric Standard Model (MSSM) are discussed.

Motivated by the μ-problem and the axion solution to the strong CP-problem, we extend the MSSM with one more chiral singlet field X ew . The underlying PQ-symmetry allows only one more renormalizable term X ew Hu Hd in the superpotential. The spectrum of the Higgs system includes a light pseudoscalar aX (in addition to the standard CP-even Higgs boson), predominantly decaying to two photons: aX →γγ. Both Higgs bosons might be in the range accessible to current LHC experiments.

One loop mediated charged Higgs bosons decays H± → W±V, V = Z, γ are studied in the Minimal Supersymmetric Standard Model (MSSM) with and without CP violating phases. We evaluate the MSSM contributions to these processes taking into account B → Xsγ constraint as well as experimental constraints on the MSSM parameters. In the MSSM, we found that in the intermediate range of tan β ≲ 10 and for large At and large μ, where the lightest top squark becomes very light and hence non-decoupled, the branching ratio of H± → W±Z can be of the order 10−3 while the branching ratio of H± → W±γ is of the order 10−5. We found also that the CP violating phases of soft SUSY parameters can modify the branching ratio by about one order of magnitude. We also show that MSSM with CP violating phases lead to CP-violating asymmetry in the decays H+ → W+V and H− → W−V. Such CP asymmetry can be rather large and can reach 80% in some region of parameter space.
