Lepton Phenomenology in Flavour Deconstruction with Anarchic Neutrinos

Flavour Deconstruction refers to a framework where the three fermion families are charged under non-universal gauge groups. Such Standard Model extensions have been proven to be capable of explaining flavour hierarchies among charged fermions. Recently, it has been shown that also neutrino anarchy can be realized within flavour-deconstructed models exploiting a seesaw mechanism. The present work aims to investigate the phenomenological implications of flavour deconstruction in the leptonic sector. In particular, we show that lepton-flavor-violating processes in rare muon decays are among the best probes of our scenario. Despite the large number of UV parameters in a general setup, we identify a limited set of combinations relevant to phenomenology. Specifically, we classify flavour-deconstructed models with neutrino anarchy and determine the minimum new-physics scale required for their viability. Notably, for certain models, it can be as low as a few TeV.
