Abstract:
In this paper, we calculated the supersymmetric contributions to the branching ratios and CP-violating asymmetries of the four B→Kπ decays in both the general and the constrained minimal supergravity (mSUGRA) model. Within the considered parameter space, we found that (a) the phase ϕμin the general mSUGRA model is strongly constrained by the data of the electron and neutron electric dipole moment and the data of B→Xsγ decay: ϕμ<0.1 (<10-3) for the case of small (large) tan β, but no limit on the phase ϕAcan be derived from the above data; (b) in both the general and the constrained mSUGRA model, the SUSY contributions are not large enough to explain the observed B→Kπ puzzle.

Abstract:
By employing the QCD factorization approach, we calculated the new physics contributions to the two-body charmless hadronic decays B → M1M2 (Mi refers to light pseudo-scalar or vector light mesons) in the minimal supergravity (mSUGRA) model. In this talk we present the major numerical results and phenomenological discussions about these eighty decay channels.

Abstract:
This study provides a brief overview of low energy supersymmetry (SUSY) in light of current experimental constraints, such as collider searches, dark matter searches, and muon g−2 measurements. In addition, we survey a variety of low energy supersymmetric models: the phenomenological minimal supersymmetric model (MSSM); the supersymmetric models with cut-off-scale boundary conditions, i.e., the minimal supergravity (mSUGRA) or the constrained MSSM (CMSSM), the gauge mediation of SUSY breaking (GMSB), and the anomaly mediation of SUSY breaking (AMSB), as well as their extensions. The conclusion is that the low energy SUSY can survive all current experimental constraints and remains compelling, albeit suffering from a slight fine-tuning problem. The advanced models such as mSUGRA, GMSB, and AMSB need to be extended if the muon g−2 anomaly comes from new physics.

Abstract:
No-scale supergravity is a framework where it is possible to naturally explain radiative electroweak symmetry breaking and correlate it with the effective SUSY breaking scale. Many string compactifications have a classical no-scale structure, resulting in a one-parameter model (OPM) for the supersymmetry breaking soft terms, which results in a highly constrained subset of mSUGRA. We investigate the allowed supersymmetry parameter space for a generic one-parameter model taking into account the most recent experimental constraints. We also survey the possible signatures which may be observable at the Large Hadron Collider (LHC). Finally, we compare collider signatures of OPM to those from a model with non-universal soft terms, in particular those of an intersecting D6-brane model.
