In this seminar, I will review the status of present and future bounds on muonic lepton flavour violating transitions in the context of an effective-field theory defined below the electroweak scale. A specific focus will be set on the phenomenology of μ→eγ, μ→3e transitions and coherent μ→e nuclear conversion in the light of current and future experiments. I will show how to recast the experimental limits into bounds at higher scales, then I will stress that the interplay between the various experiments is crucial to cover all corners of the parameter space. Furthermore, I will apply the same approach to lepton electric dipole moment and list the associated bounds on effective coefficients defined at high energy.
