Supersymmetric Models With Tanβ Close to Unity
Within the framework of supersymmetric grand unification, estimates of the b quark mass based on the asymptotic relation mb ≃ mτ single out the region with tanβ close to unity, particularly if mt(mt) < ∼ 170 GeV . We explore the radiative breaking of the electroweak symmetry and the associated sparticle and higgs spectroscopy in models with 1 < tanβ < ∼ 1.6. The lightest scalar higgs is expecte...
متن کاملhep-ph/0107333 Supersymmetric corrections to Higgs decays and b → sγ for large tan β
If tan β is large, supersymmetric QCD corrections can become large, putting naive perturbation theory into doubt. I show how these tan β-enhanced corrections can be controlled to all orders in αs tan β. The result is shown for the decays H + → tb and b → sγ. 1 Large corrections to all orders The Minimal Supersymmetric Standard Model (MSSM) contains two Higgs doublets H u and H d. Their neutral ...

متن کاملsγ and supersymmetry with large tan β
We discuss the constraints on the supersymmetric parameter space from the decay mode b → sγ for large values of tan β. We improve the theoretical prediction for the decay rate by summing very large radiative corrections to all orders in perturbation theory. This extends the validity of the perturbative calculation to the large tanβ regime. This resummation of terms of order α s tan β is based o...
متن کاملHiggs Boson Interactions in Supersymmetric Theories with Large Tan
We show that radiative corrections to the Higgs potential in supersymmetric theories with large tan generically lead to large diierences in the light Higgs boson decay branching fractions compared to those of the standard model Higgs boson. In contrast, the light Higgs boson production rates are largely unaaected. We identify W h associated production followed by Higgs boson decays to photons o...
