Dirac or inverse seesaw neutrino masses with B−L gauge symmetry and S3 flavor symmetry

Many studies have been made on extensions of the standard model with B−L gauge symmetry. The addition of three singlet (right-handed) neutrinos renders it anomaly-free. It has always been assumed that the spontaneous breaking of B−L is accomplished by a singlet scalar field carrying two units of B−L...
