Comments on General Gauge Mediation

Understand

There has been interest in generalizing models of gauge mediation of supersymmetry breaking.

• As shown by Meade, Seiberg, and Shih (MSS), the soft masses of general gauge mediation can be expressed in terms of the current two-point functions of the susy-breaking sector.
• We here give a simple extension of their result which provides, for general gauge mediation, the full effective potential for squark pseudo-D-flat directions.
• The effective potential reduces to the sfermion soft masses near the origin, and the full potential, away from the origin, can be useful for cosmological applications.
