Signals of anomaly mediated supersymmetry breaking in an e − γ collider
We study the signatures of minimal anomaly mediated supersymmetry breaking in an eγ collider. We demonstrate that the associated production of a sneutrino with the lightest chargino leads to a substantially large signal size. The background is negligibly small, though. Even more interestingly, a measurement of the fundamental supersymmetry breaking parameters could be possible. PACS NOS. : 12.6...
متن کاملAnomaly Mediated Supersymmetry Breaking and Its Test in Linear Colliders
Signatures of anomaly mediated supersymmetry breaking in linear colliders are briefly reviewed after presenting an outline of the theoretical framework. A unique and distinct feature of a large class of models of this type is a winolike chargino which is very closely degenerate in mass with the lightest neutralino. The very slow decay of this chargino results in a heavily ionizing charged track...
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 کاملFlavour Violation in Anomaly Mediated Supersymmetry Breaking
We study squark flavour violation in the anomaly mediated supersymmetry broken (AMSB) minimal supersymmetric standard model. Analytical expressions for the three-generational squark mass matrices are derived. We show that the anomaly-induced soft breaking terms have a decreasing amount of squark flavour violation when running from the GUT to the weak scale. Taking into account intergenerational...
متن کاملRadius Stabilization and Anomaly-Mediated Supersymmetry Breaking
We analyze in detail a specific 5-dimensional realization of a ‘brane-universe’ scenario where the visible and hidden sectors are localized on spatially separated 3-branes coupled only by supergravity, with supersymmetry breaking originating in the hidden sector. Although general power counting allows order 1/M Planck contact terms between the two sectors in the 4-dimensional theory from exchan...
