Description:

In the search for New Physics, one of the most promising avenues are lepton flavor violating (LFV) processes, which suffer from an extreme GIM suppression due to the smallness of neutrino masses. As a consequence, they have been the subject of an intensive experimental effort. Furthermore, it has become customary to parametrise the effects of heavy New Physics in these processes within the Effective Field Theory (EFT), as they usually involve energies substantially below the electroweak scale. However, since the amount of such effective operators is usually rather large, it is common to consider the presence of one single operator at a time. Here we go beyond this assumption and leverage the plethora of observables to derive global bounds on the relevant effective operators and asses their complementarity in efficiently constraining their parameter space.
