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 Standard Model
We present a detailed and complete calculation of the loop corrections to the mass difference ∆m B 0 d /m B 0 d. We include charginos and scalar up quarks as well as gluinos and scalar down quarks on the relevant loop diagrams. We include the mixings of the charginos and of the scalar partners of the left and right handed quarks. We find that the gluino contribution to this quantity is importan...
متن کاملMinimal Nonminimal Supersymmetric Standard Model
We review the basic field-theoretic and phenomenological features of the recently introduced Minimal Nonminimal Supersymmetric Standard Model (MNSSM). The introduced model is the simplest and most economic version among the proposed nonminimal supersymmetric models, in which the so-called μ-problem can be successfully addressed. As opposed to the MSSM and the frequently-discussed NMSSM, the MNS...
