Charged lepton flavour violation from inverse seesaw with flavour and CP symmetries
We study charged lepton flavour violation in a scenario in which light neutrino masses are generated via the inverse seesaw mechanism with 3+3 gauge singlet fermions, and , , = 1, 2, 3. Lepton mixing is predicted with the help of the flavour symmetries Δ(3 2) and Δ(6 2) combined with CP. In the neut...

| Sumario: | We study charged lepton flavour violation in a scenario in which light neutrino masses are generated via the inverse seesaw mechanism with 3+3 gauge singlet fermions, and , , = 1, 2, 3. Lepton mixing is predicted with the help of the flavour symmetries Δ(3 2) and Δ(6 2) combined with CP. In the neutral lepton sector, the non-trivial flavour structure is only encoded in the Dirac neutrino Yukawa matrix (the coupling relating left-handed lepton doublets and gauge singlets ). Current experimental bounds on the processes → , → 3 , − conversion in nuclei and the tau lepton decays → and → 3, = , , do not constrain the considered parameter space of this scenario. Prospective limits on the decay → 3 and − conversion in aluminium instead can markedly reduce the available parameter space. We also comment on the effects of the heavy sterile states on light neutrino masses and lepton mixing. |
