# Dirac or Inverse Seesaw Neutrino Masses from Gauged B - L Symmetry

@article{Ma2015DiracOI, title={Dirac or Inverse Seesaw Neutrino Masses from Gauged B - L Symmetry}, author={Ernest Ma and Rahul Srivastava}, journal={arXiv: High Energy Physics - Phenomenology}, year={2015} }

The gauged $B - L$ symmetry is one of the simplest and well studied extension of standard model. In the conventional case, addition of three singlet right handed neutrinos each transforming as $-1$ under the $B - L$ symmetry renders it anomaly free. It is usually assumed that the $B - L$ symmetry is spontaneously broken by a singlet scalar having two units of $B - L$ charge, resulting in a natural implementation of Majorana seesaw mechanism for neutrinos. However, as we discuss in this…
