Flavor Violation

Superheavy neutrinos can, via the seesaw model, provide a mechanism for lepton number violation. If they are combined with flavor violation as characterized by the Froggatt–Nielsen mechanism, then the phenomenology for the neutrinos in oscillation experiments, neutrinoless double beta decay, and other experiments can be described by a relatively few number of parameters. We describe the low-energy neutrino mass matrix and show that the results are consistent with currently available data.

The μνSSM, one of supersymmetric extensions of the Standard Model, introduces three right-handed neutrino superfields to solve the μ problem and violates lepton number. Within framework of the μνSSM, we investigate the lepton flavor violating (LFV) processes [Formula: see text] with slepton flavor mixing. Simultaneously, we consider the LFV processes [Formula: see text] and muon conversion to electron in nuclei.

Lepton Number Violating

Dark, chiral fermions carrying lepton flavor quantum numbers are natural candidates for freeze-in. Small couplings with the Standard Model fermions of the order of lepton Yukawas are `automatic' in the limit of Minimal Flavor Violation. In the absence of total lepton number violating interactions, particles with certain representations under the flavor group remain absolutely stable. For masses in the GeV-TeV range, the simplest model with three flavors, leads to signals at future direct detection experiments like DARWIN. Interestingly, freeze-in with a smaller flavor group such as SU(2) is already being probed by XENON1T.
