"Multi-messenger probes of the nature of neutrino mass "

Bhupal Dev , Washington University
[Host: Julian Heeck]

Whether neutrinos are Majorana or Dirac particles is an open question. Theoretically, it is also possible that neutrinos are pseudo-Dirac, which are fundamentally Majorana fermions, but essentially act like Dirac fermions in most experimental settings, due to extremely small active-sterile mass splitting. Such small values of mass splitting can only be accessed via active-sterile oscillations over an astrophysical baseline, or via decays of neutrinos over a cosmological time scale. In this talk, I will use the multi-messenger observation of high-energy neutrino sources and the excess radio background detection to probe two different regimes of pseudo-Dirac neutrino parameter space.
