Two-Loop Neutrino Mass Generation through Leptoquarks

Abstract

We present a new model of radiative neutrino mass generation wherein TeV scale leptoguark scalars induce tiny neutrino masses as two-loop radiative corrections. The neutrino oscillation parameter \sin^2θ_{13} is predicted to be close to the current experimental limit within the model. Rare lepton flavor violating processes mediated by leptoquarks have an interesting pattern: μ-> e γ$ may be suppressed, while μ-> 3 e and μ-e conversion in nuclei are within reach of the next generation experiments. New CP violating contributions to B_s- \bar{B}_s mixing via leptoquark box diagrams are in a range that can explain the recently reported discrepancy with the standard model. D_s^- -> \ell^- νdecays mediated by leptoquarks brings theory and experiment closer, removing an observed 2 sigma anomaly. Muon g-2 receives new positive contributions, which can resolve the discrepancy between theory and experiment. The leptoquarks of the model are accessible to the LHC, and their decay branching ratios probe neutrino oscillation parameters.
