Mediating SUSY BreakingBreaking the MSSMSeparate out the supersymmetry breaking sector from the MSSMsector, and couple them with messenger fields:The phenomenology, i.e. the pattern of soft terms, depends quitehighly on the form of these messengers.(I.P.P.P. — Durham University) SUSY Breaking Heidelberg 19 / 27
Mediating SUSY BreakingCommon Messenger SectorsGravity mediation — Planck suppressed operators◮ FCNC◮ Universality assumptions ⇒ mSUGRAGauge mediation — charged under SM gauge fields◮ flavour blind◮ µ problemAnomaly mediation — supergravityGaugino mediation — extra dimensions. . .(I.P.P.P. — Durham University) SUSY Breaking Heidelberg 20 / 27
