We propose a dynamical scoto-seesaw mechanism using a gauged $B-L$ symmetry. Dark matter is reconciled with neutrino mass generation, in such a way that the atmospheric scale arises through the standard seesaw,
while the solar scale is scotogenic, arising radiatively from the exchange of dark sector particles. This way we explain the solar-to-atmospheric scale ratio. The TeV-scale seesaw...
Radiative seesaw models are examples of testable extensions of the SM to explain the light neutrino masses. In radiative seesaw models at 1-loop level, such as the popular scotogenic model, in order to successfully reproduce neutrino masses and mixing, one has to rely either on unnaturally small Yukawa couplings or on a very small mass splitting between the CP-even and CP-odd components of the...
Lepton number violation is present in models of leptogenesis and Majorana neutrino masses, but has so far not been observed experimentally. Beyond the conventional seesaw mechanisms, lepton number violation may be induced at a higher mass dimension, e.g. from effective operators at mass dimension 7. Just like the seesaw mechanisms generate the dimension-5 Weinberg operator, these dimension-7...
We have derived a general and explicit expression for the Jarlskog invariant of CP violation in flavor oscillations of three active neutrinos by using the 18 original parameters in the canonical seesaw mechanism (i.e., 3 heavy Majorana neutrino masses, 9 active-sterile flavor mixing angles and 6 CP-violaing phases). This novel analytical result provides the first model-independent window to...
In this talk I will present the role of the often neglected "mixed" scattering processes within realistic hybrid type I + Type II seesaw framework.
