Radiative Neutrino Masses: Rich Nu Connections
Alexander Merle (MPI Munich)

In this talk, I will discuss the rich phenomenology of radiative models, which generate a neutrino mass only at loop level. After giving an introduction to the principal ideas behind this class of theories, I will highlight certain aspects of particular types of settings. On the one hand, I will discuss how strongly renormalisation group running can be enhanced in radiative models, with the probably most popular 1-loop model serving as example. On the other hand, I will focus strongly on the complementarity between probing these models from both sides, low and high energies, by connecting the information available from neutrinos/LFN/LFV and collider physics. As we will see, radiative models can strongly relate both experimental sides, thereby opening up the possibility for a comprehensive study of these models.
