Abstract |
In split-family SUSY, one can use a U(2)(3) symmetry to protect flavour observables in the quark sector from SUSY contributions. However, attempts to extend this procedure to the lepton sector by using an analogous U(2)(5) symmetry fail to reproduce the neutrino data without introducing some form of fine-tuning. In this work, we solve this problem by shifting the U(2)(2) symmetry acting on leptons towards the second and third generations. This allows neutrino data to be reproduced without much difficulties, as well as protecting the leptonic flavour observables from SUSY. Key signatures are a μ-> e gamma branching ratio possibly observable in the near future, as well as having selectrons as the lightest sleptons. |
