Anomaly Mediation , Fayet - Iliopoulos D - terms and precision sparticle spectra
نویسنده
چکیده
We consider the sparticle spectra that arise when anomaly mediation is the source of supersymmetry-breaking and the tachyonic slepton problem is solved by a Fayet-Iliopoulos D-term. We also show how this can lead to a minimal viable extension of anomaly mediation, in which the gauge symmetry associated with this D-term is broken at very high energies, leaving as its footprint in the low energy theory only the required D-terms and seesaw neutrino masses.

Anomaly Mediation , Fayet - Iliopoulos D - terms and the Renormalisation Group
We address renormalisation group evolution issues that arise in the Anomaly Mediated Supersymmetry Breaking scenario when the tachyonic slepton problem is resolved by Fayet-Iliopoulos term contributions. We present typical sparticle spectra both for the original formulation of this idea and an alternative using Fayet-Iliopoulos terms for a U 1 compatible with a straightforward GUT embedding.

متن کاملFayet - Iliopoulos D - terms and anomaly mediated supersymmetry breaking
We show that in a minimal extension of the MSSM by means of an extra U 1 gauge group, the negative mass-squared problem characteristic of the Anomaly Mediated Super-symmetry Breaking scenario is naturally solved by means of Fayet-Iliopoulos D-terms. We derive a set of sum rules for the sparticle masses which are consequences of the resulting framework.
متن کاملFayet-Iliopoulos D-terms, neutrino masses and anomaly mediated supersymmetry breaking
We explore, in the context of the MSSM generalised to admit massive neutrinos, an extension of the Anomaly Mediated Supersymmetry Breaking solution for the soft scalar masses to incorporate Fayet-Iliopoulos D-terms. The slepton mass problem characteristic of the scenario is resolved, and the fermion mass hierarchy is explained via the FroggattNielsen mechanism. FCNC problems are evaded by a com...
متن کاملAnomaly Cancellation in Supergravity with Fayet-Iliopoulos Couplings
We review and clarify the cancellation conditions for gauge anomalies which occur when N = 1, D = 4 supergravity is coupled to a Kähler non-linear sigma-model with gauged isometries and Fayet-Iliopoulos couplings. For a flat sigma-model target space and vanishing Fayet-Iliopoulos couplings, consistency requires just the conventional anomaly cancellation conditions. A consistent model with non-v...
