SUSY breaking mechanisms SUSY spontaneous breaking in “hidden” sector, communicated by “mediator” fields 3 standard mediation mechanisms: (1) Gravity (2) Gauge (3) Anomaly
“Deflected” mirage mediation Parameter space: 2 mass scale: M 0 M mess 4 dimensionless: N α m α g tanβ 1 sign [L.L. Everett, I.W. Kim, et al., hep-ph/ L.L. Everett, I.W. Kim, et al., hep-ph/ ] Stabilization of T & X moduli String setup: generically includes SM singlet X (vev F X ) + messengers (SM charged exotic vector pairs) These ingredients (after T and X stabilization) can lead to gauge mediation terms that can be comparable to the anomaly and gravity mediation contributions of mirage mediation! And also
Why “deflected”? mirage unification deflection Deflection can be dramatic!
DMM Phenomenology RG running + Mass spectrum Mirage unification behavior: deflection of mirage unification scale generically only present in gaugino sector Mass Spectrum: –Compressed vs. stretched spectrum –Gluino not always the heaviest –Light heavy Higgs combinations: HAH ±, AHH ±

Summary DMM: Rich Framework for SUSY breaking. Theoretically- motivated scenario for nonuniversal SUSY breaking models (top-down approach) Many general models with only a few new parameters –2 mass scales, 4+ dimensionless parameters, 1 sign (compare mSUGRA: 3 mass scales, 1 dimensionless, 1 sign) New features in phenomenology
