Higgs Particle Decays in Supersymmetry

الأصل · EN

We present a detailed study of the decays of the Higgs bosons H+, H⁰, and A⁰ within the Minimal Supersymmetric Standard Model including SUSY--QCD corrections. We find that the supersymmetric modes t b (t t, and for large β b b) can dominate the H+ (H⁰, A⁰) decays in a wide range of the model parameters due to the large Yukawa couplings and mixings of t and b. Compared to the conventional modes H+ → τ+ ντ, t b, and H⁰, A⁰ → t t, b b, the supersymmetric modes can have an important impact on the Higgs boson searches at future colliders.
