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

TL;DR

This paper proposes a TeV-scale model with extra scalars and fermions that explains neutrino masses, muon g-2, dark matter, lithium problem, and leptogenesis, and can be tested at collider experiments.

Contribution

It introduces a new TeV-scale model with specific particles and symmetries that simultaneously addresses multiple outstanding issues in particle physics and cosmology.

Findings

Neutrino masses generated via one-loop effects.

Muon g-2 anomaly explained within the model.

Dark matter and lithium problem addressed.

Abstract

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. This scenario can be tested at LHC and/or future experiments.
