Gluino - mediated FCNCs in the MSSM with large tan β

چکیده
We present results of our study of tanβ -enhanced loop corrections in the Minimal Supersymmetric Standard Model (MSSM) with Minimal Flavour Violation (MFV). We demonstrate that these corrections induce flavour changing neutral current (FCNC) gluino couplings which have a large impact on the Wilson coefficient C8 of the chromomagnetic operator. To illustrate the phenomenological consequences of this gluino-squark contribution to C8, we briefly discuss its effect on the mixing-induced CP asymmetry in the decay Bd → φKS.

متن کاملsνν̄ decay in the MSSM : Implication of b → sγ at large tan β
The decay b → sνν̄ is discussed in the minimal supersymmetric standard model with general flavor mixing for squarks, at large tan β. In this case, in addition to the chargino loop contributions which were analyzed in previous studies, tan β-enhanced contributions from the gluino and charged Higgs boson loops might become sizable compared with the standard model contribution, at least in principl...
متن کاملM ar 1 99 8 Gluon and gluino penguins and the charmless decays of the b quark
Gluon mediated exclusive hadronic decays of b quarks are studied within the standard model (SM) and the constrained minimally supersymmetric standard model (MSSM). For all allowed regions of the MSSM parameter space (A, tan β, m 0 , m 1/2) the penguin magnetic dipole form factor F R 2 is dominant over the electric dipole and can be larger than the magnetic dipole form factor of the SM. However,...
متن کاملA Light Bottom Squark in the MSSM
We study the compatibility of a light bottom squark Mb̃ < O(10GeV ) in the unconstrained MSSM. We consider the one-loop radiative corrections which are large for a heavy gluino (>O(150GeV )). We then consider the renormalization group flow up to the Grand Unified scale. For most regions of the parameter space with a light sbottom we find colour and charge breaking minima. Only a small window in ...

We consider the infrared quasi fixed point solutions of the renormalization group equations for the Yukawa couplings and soft supersymmetry breaking parameters in the MSSM in the large tan β regime. The existence of IR quasi fixed points together with the values of gauge couplings, third generation quarks, lepton and Z-boson masses allows one to predict masses of the Higgs bosons and SUSY parti...
