In models with dynamical supersymmetry breaking in the hidden sector, the gaugino masses in the observable sector have been believed to be extremely suppressed (below 1 keV), unless there is a gauge singlet in the hidden sector with specific couplings to the observable sector gauge multiplets. We point out that there is a pure supergravity contribution to gaugino masses at the quantum level arising from the superconformal anomaly. Our results are valid to all orders in perturbation theory and… 
Dirac gaugino masses and supersoft supersymmetry breaking
We introduce a new supersymmetric extension of the standard model in which the gauge sector contains complete N = 2 supersymmetry multiplets. Supersymmetry breaking from the D-term vev of a hidden
(Extra)ordinary gauge/anomaly mediation
We study anomaly mediation models with gauge mediation effects from messengers which have a general renormalizable mass matrix with a supersymmetry-breaking spurion. Our models lead to a rich
Nonstandard supersymmetry breaking and Dirac gaugino masses without supersoftness
I consider models in which non-standard supersymmetry breaking terms, including Dirac gaugino masses, arise from F-term breaking mediated by operators with a $1/M^3$ suppression. In these models, the
Radion mediated supersymmetry breaking
We point out that in supersymmetric theories with extra dimensions, radius stabilization can give rise to a VEV for the F component of the radius modulus. This gives an important contribution to
Mixed gauge and anomaly mediation from new physics at 10 TeV
In the context of anomaly-mediated supersymmetry breaking, it is natural for vectorlike fields and singlets to have supersymmetry breaking masses of order 10 TeV, and therefore act as messengers of
Supersymmetry breaking induced by radiative corrections
A bstractWe show that simultaneous gauge and supersymmetry breaking can be induced by radiative corrections, à la Coleman-Weinberg. When a certain correlation among the superpotential parameters is
Gaugino mediated supersymmetry breaking
We consider supersymmetric theories where the standard-model quark and lepton fields are localized on a `3-brane' in extra dimensions, while the gauge and Higgs fields propagate in the bulk. If
Gauge vs. gravity mediation in models with anomalous U(1)'s
In an attempt to implement gauge mediation in string theory, we study string effective supergravity models of supersymmetry breaking, containing anomalous gauge factors. We discuss subtleties related
Towards 5D Grand Unification without SUSY Flavor Problem
We consider the renormalization group approach to the SUSY flavor problem in the supersymmetric SU(5) model with one extra dimension. In higher dimensional SUSY gauge theories, it has been recently
