Neutrino masses, muon g-2, dark matter, lithium problem, and leptogenesis at TeV-scale

Understand

Observational evidences of nonzero neutrino masses and the existence of dark matter request physics beyond standard model.

• A model with extra scalars and leptonic vector-like fermions is introduced.
• By imposing a Z_2 symmetry, the neutrino masses as well as anomalous muon magnetic moment can be generated via one-loop effects at TeV-scale.
• An effort of explaining dark matter, Lithium problem, and leptogenesis is presented.
