Flavor Physics in the Supergravity Model

چکیده
Phenomenological aspects of avor changing processes are considered in the context of the supergravity model. Various avor changing neutral current processes in B and K decays are calculated in such models. For lepton avor violating processes the + ! ee branching ratio and the T odd triple vector correlation for the + ! e + e + e ? process are investigated in the SU(5) SUSY GUT. Possibility to nd SUSY eeects through these Flavor changing processes in future experiments are also discussed.

Flavor Physics in the Supergravity Model 1
Phenomenological aspects of flavor changing processes are considered in the context of the supergravity model. Various flavor changing neutral current processes in B and K decays are calculated in such models. For lepton flavor violating processes the μ → eγ branching ratio and the T odd triple vector correlation for the μ → eee process are investigated in the SU(5) SUSY GUT. Possibility to fin...
متن کاملSPICE: Simulation Package for Including Flavor in Collider Events
We describe SPICE: Simulation Package for Including Flavor in Collider Events. SPICE takes as input two ingredients: a standard flavor-conserving supersymmetric spectrum and a set of flavorviolating slepton mass parameters, both of which are specified at some high “mediation” scale. SPICE then combines these two ingredients to form a flavor-violating model, determines the resulting low-energy s...

We propose a geometric theory of flavor based on the discrete group (S3) , in the context of the minimal supersymmetric standard model. The group treats three objects symmetrically, while making fundamental distinctions between the generations. The top quark is the only heavy quark in the symmetry limit, and the first and second generation squarks are degenerate. The hierarchical nature of Yuka...
متن کاملExploring Flavor Structure of SUSY Breaking from B Decays and the Unitarity Triangle
We study effects of SUSY particles in the unitarity triangle analysis and the CP asymmetries in b → s decays. We consider three different SUSY models, the minimal supergravity, SU(5) SUSY GUT with right-handed neutrinos, and MSSM with U(2) flavor symmetry, and show that the patterns and correlations of deviations from the standard model will be useful to discriminate the different SUSY models i...
متن کاملEffective Lagrangian for sbg and sbγ Vertices in the mSUGRA model
Complete expressions of the sbg and sbγ vertices are derived in the framework of supersymmetry with minimal flavor violation. With the minimal supergravity (mSUGRA) model, a numerical analysis of the supersymmetric contributions to the Wilson Coefficients at the weak scale is presented. PACS numbers: 11.30.Er, 12.15.Ff, 12.60.Jv, 13.10+q.
