Confronting a new three-loop seesaw model with the 750 GeV diphoton excess
Confronting a new three-loop seesaw model with the 750 GeV diphoton excess
We propose a new type of radiative neutrino model with a local dark $U(1)$ symmetry, where neutrino masses are induced at the three-loop level, and discuss the muon anomalous magnetic moment and dark matter candidates therein. By allowing hypercharges larger than $3/2$ for new fields that contribute to the neutrino …
