Gauge B-L Model of Radiative Neutrino Mass with Multipartite Dark Matter
Abstract
We propose an extension of the standard model of quarks and leptons to include gauge B-L symmetry with an exotic array of neutral fermion singlets for anomaly cancellation. With the addition of suitable scalars also transforming under U(1)B-L, this becomes a model of radiative seesaw neutrino mass with possible multipartite dark matter. If leptoquark fermions are added, necessarily also transforming under B-L, the diphoton excess at 750 GeV, recently observed at the Large Hadron Collider, may also be explained.
