Supernatural Supersymmetry: Phenomenological Implications of Anomaly-Mediated Supersymmetry Breaking
We discuss the phenomenology of supersymmetric models in which supersymmetry breaking terms are induced by the super-Weyl anomaly. Such a scenario is envisioned to arise when supersymmetry breaking takes place in another world, i.e., on another brane. We review the anomaly-mediated framework and study in detail the minimal anomaly-mediated model parametrized by only 3 + 1 parameters: Maux, m0, ...
متن کاملAnomaly Mediated Supersymmetry Breaking Demystified
We reinterpret anomaly-mediated supersymmetry breaking from a fieldtheoretic perspective in which superconformal anomalies couple to either the chiral compensator or the U(1)R vector superfield. As supersymmetry in the hidden sector is spontaneously broken by non-vanishing vacuum expectation values of the chiral compensator F-term and/or the U(1)R vector superfield D-term, the soft breakdown of...
متن کاملPhenomenological Implications of Low Energy Supersymmetry Breaking
The experimental signatures for low energy supersymmetry breaking are presented. The lightest standard model superpartner is unstable and decays to its partner plus a Goldstino, G. For a supersymmetry breaking scale below a few 1000 TeV this decay can take place within a detector, leading to very distinctive signatures. If a neutralino is the lightest standard model superpartner it decays by χ1...
متن کاملAnomaly Mediated Supersymmetry Breaking without R – Parity
We analyze the low energy features of a supersymmetric standard model where the anomaly–induced contributions to the soft parameters are dominant in a scenario with bilinear R–parity violation. This class of models leads to mixings between the standard model particles and supersymmetric ones which change the low energy phenomenology and searches for supersymmetry. In addition, R–parity violatio...
متن کاملAnomaly-Mediated Supersymmetry Breaking with Axion
We construct hadronic axion models in the framework of the anomaly-mediated supersymmetry breaking scenario. If the Peccei-Quinn symmetry breaking is related to the supersymmetry breaking, mass spectrum of the minimal anomaly-mediated scenario is modified, which may solve the negative slepton mass problem in the minimal anomaly-mediated model. We find several classes of phenomenologically viabl...
