4 Research and Collaborations Signature of SUSY in pion decay Michael RamseyMusolf (Caltech), Sean Tulin (Caltech) Pion Leptonic Decays and Supersymmetry M. RamseyMusolf, S. Su and S. Tulin, arxiv: [hepph], submitted to Phys. Rev. D = +. It is clear that R SUSY SUSY e/µ Loop is largest in 10 x 10!3 here either (1) µ is small, m ul is large, and ontributions 0.002to Re/µ SUSY are from V + L, 8 large, m ul is small, and the largest contri 6 Re/µ SUSY is from B. If both µ and m ul are R SUSY 4 e/µ can still be very small due to canven though both V + L and B contrilarge individually. More precisely, to satisfy 2 0 d either µ 150 GeV and m ul 175 GeV, GeV and m ul 200 GeV (for our particuf fixed parameters, which have been chosen !2 RPV ward large Re/µ SUSY ).! ! " k x 10!3 S.
