Naturally small Dirac neutrino mass and B-L dark matter
The hosts discussed a paper titled "Naturally small Dirac neutrino mass and B-L dark matter." The authors propose a mechanism to achieve naturally small neutrino masses without fine-tuning. They presented two distinct scenarios for dark matter: one involving a stable vector-like fermion (Dirac DM) and another involving chiral fermions (Majorana DM), both offering testable predictions like gravitational waves.
