Viable Supersymmetry and Leptogenesis with Anomaly Mediation
The seesaw mechanism that explains the small neutrino masses comes naturally with supersymmetric (SUSY) grand unification and leptogenesis. However, the framework suffers from the SUSY flavor and CP problems, and has a severe cosmological gravitino problem. We propose anomaly mediation as a simple solution to all these problems, which is viable once supplemented by the D-terms for U(1)Y and U(1...
متن کاملElectroweak Symmetry Breaking via UV Insensitive Anomaly Mediation
Anomaly mediation solves the supersymmetric flavor and CP problems. This is because the superconformal anomaly dictates that supersymmetry breaking is transmitted through nearly flavor-blind infrared physics that is highly predictive and UV insensitive. Slepton mass squareds, however, are predicted to be negative. This can be solved by adding D-terms for U(1)Y and U(1)B−L while retaining the UV...
متن کاملGravity Mediation of Supersymmetry Breaking with Dynamical Metastability
We argue that the Polonyi problem can be avoided when our supersymmetrybreaking vacuum is surrounded by many supersymmetric vacua. We construct a dynamical class of supersymmetry-breaking models to demonstrate our point. These models naturally predict a small deviation from the standard big-bang nucleosynthesis.
متن کاملSupersymmetry and Electroweak Leptonic Observables
We study vertex corrections to the leptonic electroweak observables in the general MSSM at tan β <∼ 35. In particular, we address the question of whether supersymmetry can be responsible for the observed 2σ deviation from the Standard Model prediction in the invisible width of the Z. We find that the presence of a light (around 100 GeV) chargino and sleptons hinted by the gμ-2 measurements make...
متن کاملSupersymmetry at the Electroweak
The simplest interpretation of the global success of the Standard Model is that new physics decouples well above the electroweak scale. Supersymmetric extension of the Standard Model offers the possibility of light chargino and the right-handed stop (with masses below MZ), and still maintaining the successful predictions of the Standard Model. The value of Rb can then be enhanced up to ∼ 0.218 ...
