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…

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…

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…

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…
