mixing in the minimal supergravity model

We investigate the effect of SUSY phases ( θA and θμ ) on the B 0 d−B 0 d mixing in the minimal supergravity model. It is known that the complex phase θA = arg(A) ( A is the universal coefficient of the trilinear scalar couplings ) is essentially unconstrained by the electric dipole moment experiment, while the phase θμ = arg(μ) ( μ is the supersymmetric Higgsino mass ) is strongly constrained ...

ǫK parameter in the minimal supergravity model

B–B 0 mixing and a CP violation parameter in K–K 0 mixing ǫK are studied in the minimal supergravity model. We solve the one-loop renormalization group equations for the minimal supersymmetric standard model (MSSM) parameters numerically in order to determine the masses and mixings of the supersymmetric particles, while all off-diagonal (generation mixing) elements and phases of Yukawa coupling...

Updated constraints on the minimal supergravity model

Recently, refinements have been made on both the theoretical and experimental determinations of i.) the mass of the lightest Higgs scalar, ii.) the relic density of cold dark matter in the universe, iii.) the branching fraction for the radiative b → sγ decay, iv.) the muon anomalous magnetic moment, and v.) the flavor violating decay Bs → μ+μ−. In this work, we present constraints from each of ...

Weak Effective Lagrangian in the Minimal Flavor Violation Supersymmetry

To evaluate the weak decays of b-hadrons, the ∆B = 1 weak effective Lagrangian is the foundation. Any new physics beyond the standard model (SM) would contribute to the effective Lagrangian through the loop integration at the weak scale and evolution from the weak scale down to the hadronic scale. In this work we present a systematic analysis on the effective Lagrangian which mediates hadronic ...

A Minimal Four - Family Supergravity Model

In this work, we investigate the phenomenology of minimal four-family MSSM supergravity theories containing an additional generation (t; b; ; ) of heavy fermions along with their superpartners. We constrain the models by demanding: gauge coupling constant uni cation at high energy scales; perturbative values for all Yukawa couplings for energy scales up to the grand-uni cation scale; radiative ...
