(a) Predictions of decay rate obtained by scanning mSUGRA parameter space for and [80]. The red points correspond to PMNS-like mixing and the blue ones to CKM-like mixing. The limit established by MEG in [91] is indicated as “MEG Now,” while the label “MEG 2013” corresponds to the originally predicted sensitivity of the MEG experiment [113]. The actual upper limit is about a factor five higher [92]. (b) Allowed space in the plane, which satisfies the MEG bound. The region below the red line is excluded by direct SUSY searches performed at LHC [42–66].
