N2 - The new MEG bound on BR(μ→eγ) provides the strongest upper bound on the scale of gauge mediation of supersymmetry breaking. If, in the future, this decay is observed by MEG, the mediation scale will become known to within 1 order of magnitude, and the seesaw scale will be constrained. In such a case, contributions from Planck mediated supersymmetry breaking are likely to be non-negligible, and an interpretation in terms of purely seesaw parameters will be impossible. The recent evidence for |U e3|∼0.15 further sharpens the predictions of gauge-mediated supersymmetry breaking.
