Using an effective lagrangian description we analyze possible new physics contributions to the most relevant muon number violating processes: μ→eγ and μ-e conversion in nuclei. We identify a general class of models in which those processes are generated at one loop level and in which μ-e conversion is enhanced with respect to μ→eγ by a large ln(m2μ/Λ2), where Λ is the scale responsible for the new physics. For this wide class of models bounds on μ-e conversion constrain the scale of new physics more stringently than μ→eγ already at present and, with the expected improvements in μ-e conversion experiments, will push it upwards by about one order of magnitude more. To illustrate this general result we give an explicit model containing a doubly charged scalar and derive new bounds on its couplings to the leptons.
