Description
We have analyzed new contributions to the muon anomalous magnetic moment in a class of models that generates a naturally large transition magnetic moment for the neutrino (needed to explain the XENON1T electron recoil excess). These models are based on an approximate $SU(2)_H$ symmetry that suppresses the neutrino mass while allowing for a large neutrino transition magnetic moment. We have shown that the new scalars present in the theory with masses around $100$ GeV can yield the right sign and magnitude for the muon $g−2$ which has been confirmed recently by the Fermilab collaboration. Such a correlation between muon $g−2$ and the neutrino magnetic moment is generic in models employing leptonic family symmetry to explain a naturally large neutrino magnetic moment. We have also outlined various other experimental tests of these models at colliders. Results will be presented.
