Supersymmetric Higgs boson decays with radiative corrections

Abstract

A global analysis of the Higgs boson decay rates and branching ratios in the Minimal Supersymmetric Standard Model is performed in the framework of the earlier introduced complete one-loop renormalization scheme for the gauge boson and Higgs sectors of the model. Full one-loop corrections to the Higgs boson masses, scalar trilinear vertices and Higgs boson couplings to the neutral vector bosons are included in the calculation. Detailed results for the decays H 0 → h 0 h 0, A 0 → Z 0 h 0 and φ 0 → V i 0 V j 0 where φ 0  h 0, H 0, A 0 and V i 0 V j 0  Z 0 Z 0, Z 0 γ , γγ are presented.
