Anomaly 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...

Radius 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...

Yukawa Textures and Anomaly Mediated Supersymmetry Breaking

We present a detailed analysis of how a mixed-anomaly-free U 1 symmetry can be used to both resolve the slepton mass problem associated with Anomaly Mediated Supersymme-try Breaking and generate the fermion mass hierarchy via the Froggatt-Nielsen mechanism. Flavour changing neutral currents problems are evaded by a specific form of the Yukawa textures.

Partial Symmetry Breaking

In this paper we define partial symmetry breaking, a concept that has been used in many previous papers without being the main topic of any research. This paper is the first systematic study of partial symmetry breaking in constraint programming. We show experimentally that performing symmetry breaking with only a subset of all symmetries can result in greatly reduced run-times. We also look at...
