Minimal Supersymmetric Standard Model
In the minimal supersymmetric standard model, the Higgs sector has two unknown parameters, usually taken to be tanβ ≡ v2/v1 and mA, the mass of its one physical pseudoscalar particle. By minimizing the minimum of the Higgs potential along a certain direction in parameter space, it is shown that mA = MZ + radiative correction, and if one further plausible assumption is made, tanβ > √ 3. If there...
متن کاملMinimal Supersymmetric Standard Model
The quantity RK = Γ(K → eν)/Γ(K → μν) studied by the experiment NA62 at CERN is known to probe lepton-flavour violating (LFV) parameters of the Minimal Supersymmetric Standard Model (MSSM). A non-zero parameter δ RR can open the decay channel K → eντ and enhance RK over its Standard-Model value. In the region of the parameter space probed by NA62 the contribution from a bino-stau loop diagram i...
متن کاملMinimal Supersymmetric Standard Model
We study the inclusive rare decay B → Xd + γ in the supergravity inspired Minimal Supersymmetric Standard Model and compute the CP-asymmetry in the decay rates. We show that there exist two phenomenologically acceptable sets of SUSY parameters: for one set the CP-asymmetry has the same (positive) sign as in the Standard Model and lies in the range (5−45)% while for the other set it is negative ...
متن کاملThe Minimal Supersymmetric Leptogenesis
We reanalyze the supersymmetric leptogenesis model by one of the authors (HM) and Yanagida based on L̃ = Hu flat direction in detail. We point out that the appropriate amount of baryon asymmetry can be generated in this model with the neutrino mass matrix consistent with the atmospheric neutrino oscillation and solutions to the solar neutrino problem, preferably the small angle MSW solution. The...
متن کاملMinimal Supersymmetric Left–Right Model
We revisit the minimal supersymmetric left–right model with B−L = 2 triplet Higgs fields and show that a self–consistent picture emerges with automatic R–parity conservation even in the absence of higher dimensional operators. By computing the effective potential for the Higgs system including heavy Majorana neutrino Yukawa couplings we show that the global minimum of the model can lie in the c...
