Reach and complementarity of $\mu \to e$ searches

Abstract

In Effective Field Theory, we describe $\mu \leftrightarrow e$ flavour changing transitions using an operator basis motivated by experimental observables. In a six-dimensional subspace probed by $\mu \to e\gamma$, $\mu \to 3e$ and $\mu \to e$ conversion on nuclei, we derive constraints on the New Physics scale from past and future experiments, illustrating the complementarity of the processes in an intuitive way. We also recall that a precise determination of the scalar quark currents in the nucleon will be required to distinguish scalar $\mu \to e$ interactions on u-quarks from those on d-quarks.
