General Gauge Mediation with Gauge Messengers

Understand

We generalize the General Gauge Mediation formalism to allow for the possibility of gauge messengers.

• Gauge messengers occur when charged matter fields of the susy-breaking sector have non-zero F-terms, which leads to tree-level, susy-breaking mass splittings in the gauge fields.
• A classic example is that SU(5) / SU(3) x SU(2) x U(1) gauge fields could be gauge messengers.
• We give a completely general, model independent, current-algebra based analysis of gauge messenger mediation of susy-breaking to the visible sector.
