Mass Sum Rules and the Role of the Messenger Scale in General Gauge Mediation

Understand

In General Gauge Mediation (GGM), supersymmetry breaking is communicated to the Standard Model (MSSM) sector via gauge interactions at a high scale which we refer to as the messenger scale.

• At this scale GGM predicts certain sum rules between the MSSM sfermion masses.
• We investigate the validity and the ultimate fate of these sum rules after RG evolution down to the electroweak scale where the mass spectrum will be probed at colliders.
• We find that the sum rules hold for the first two generations.
