SUSY-Breaking Scenarios With a Mildly Violated R Symmetry

Understand

New realizations of the gravity-mediated SUSY breaking are presented consistently with an R symmetry.

• We employ monomial superpotential terms for the hidden-sector (goldstino) superfield and Kahler potentials parameterizing compact or non-compact Kahler manifolds.
• Their scalar curvature may be systematically related to the R charge of the goldstino so that Minkowski solutions without fine tuning are achieved.
• A mild violation of the R symmetry by a higher order term in the Kahler potentials allows for phenomenologically acceptable masses for the R axion.
