Neutrino Mass and Dark Matter from Gauged B$-$L Breaking

We discuss a new radiative seesaw model with the gauged B$-$L symmetry which is spontaneously broken. We improve the previous model by using the anomaly-free condition without introducing too many fermions. In our model, dark matter, tiny neutrino masses and neutrino oscillation data can be explained simultaneously, assuming the B$-$L symmetry breaking at the TeV scale.
