Rare B Decays in SUSY without R-parity
نویسنده
چکیده
We perform the complete computation of the contributions to b → s + γ, b → se+e−, b → sνeν̄e in the SUSY with bilinear R-parity violation model. We compare the results with the evaluations in the SM. From those processes, we can get some constraint on the parameters in this model. 12.60.Jv, 13.10.+q, 14.80.Ly, 13.20Jf, 12.15Ff Typeset using REVTEX

The Beauty of SUSY ∗
B physics represents a privileged place to look for supersymmetry (SUSY) through its virtual effects. Here we discuss rare B decays (b → sγ, b → sg, b → sl + l −) and B − ¯ B oscillations in the context of low-energy SUSY. We outline the variety of predictions that arise according to the choice of the SUSY extension ranging from what we call the " minimal " version of the MSSM to models without...

In this talk we discuss rare B decays (b → sγ, b → sg, b → sℓ + ℓ −), B − ¯ B oscillations and CP violation in B physics in the context of low-energy SUSY. We outline the variety of predictions that arise according to the choice of the SUSY extension ranging from what we call the " minimal " version of the MSSM to models without flavour universality or with broken R-parity. In particular, we pr...
متن کاملSUSY FLAVOR v2.5: A computational tool for FCNC and CP-violating processes in the MSSM
We present SUSY FLAVOR version 2 — a Fortran 77 program that calculates low-energy flavor observables in the general R-parity conserving MSSM. For a set of MSSM parameters as input, the code gives predictions for: 1. Electric dipole moments of the leptons and the neutron. 2. Anomalous magnetic moments (i.e. g − 2) of the leptons. 3. Radiative lepton decays (μ → eγ and τ → μγ, eγ). 4. Rare Kaon ...

متن کاملViolating R - Parity at the B - Factory
Supersymmetry without R-parity contains new tree-level contributions to B-decays. A brief summary is provided of the current experimental bounds on those tree-level contributions which are relevant to B physics. Signals to look for are outlined in the context of CP violation and rare decays. For the first time, the signature of general R-parity violating models is described. B-factory experimen...
