General messenger gauge mediation
Abstract
We discuss theories of gauge mediation in which the hidden sector consists of two subsectors which are weakly coupled to each other. One sector is made up of messengers and the other breaks supersymmetry. Each sector by itself may be strongly coupled. We provide a unifying framework for such theories and discuss their predictions in different settings. We show how this framework incorporates all known models of messengers. In the case of weaklycoupled messengers interacting with spurions through the superpotential, we prove that the sfermion masssquared is positive, and furthermore, that there is a lower bound on the ratio of the sfermion mass to the gaugino mass.
