AB  - We propose a dynamical scoto-seesaw mechanism using a gauged B – L symmetry. Dark matter is reconciled with neutrino mass generation, in such a way that the atmospheric scale arises a la seesaw, while the solar scale is scotogenic, arising radiatively from the exchange of "dark" states. This way we "explain" the solar-to-atmospheric scale ratio. The TeV-scale seesaw mediator and the two dark fermions carry different B – L charges. Dark matter stability follows from the residual matter parity that survives B – L breaking. Besides having collider tests, the model implies sizable charged lepton flavor violating (cLFV) phenomena, including Goldstone boson emission processes.
