Neutrino masses are unlikely to share the Standard Model origin of other fermion masses, with the Weinberg effective Lagrangian providing the simplest beyond-Standard-Model mechanism for small Majorana masses.

Amplifying muon-to-positron conversion in nuclei with ultralight dark matter
Ultralight scalar dark matter amplifies the lepton-flavor-violating muon-to-positron conversion rate via an effective Majorana mass m_μe, yielding new constraints on flavor-off-diagonal neutrino couplings from SINDRUM II, COMET, and Mu2e bounds.

Neutrino Masses from the Point of View of Economy and Simplicity
Neutrino masses are unlikely to share the Standard Model origin of other fermion masses, with the Weinberg effective Lagrangian providing the simplest beyond-Standard-Model mechanism for small Majorana masses.
