Phenomenology of minimal lepton flavor violation

We extend the effective theory of minimal lepton flavor violation (MLFV) by including four-lepton operators. We compute the rates for mu -> 3e and T -> 3l decays and point out several new ways to test the hypothesis of MLFV We also investigate to what extent it will be possible from (future) experimental information to pin down the contributions of different effective operators. In particular we look for experimental handles on quark-lepton operators of the type (l) over bar Gamma l x (q) over bar Gamma g by working out their contribution to hadronic processes such as tau -> mu pi(0), pi(0) -> mu(e) over bar, gamma -> tau(u) over bar as well as to purely leptonic decays such as mu -> 3e through loop effects.
