Neutrino Sector with Majorana Mass Terms and Friedberg-Lee Symmetry

Jarlskog, Cecilia LU (2008) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 77(7).
Abstract
We examine a recently proposed symmetry/condition by Friedberg and Lee in the framework where three right-handed neutrinos are added to the spectrum of the three-family Minimal Standard Model. It is found that the right-handed neutrinos are very special, with respect to this symmetry. In the symmetry limit the neutrinos are massless and that may be a hint about why they are light. Imposed as a condition and not as a full symmetry, we find that one of the three right-handed neutrinos simply decouples (has only gravitational interactions) and that there is a massless interacting neutrino. The possible relation of the model to the see-saw mechanism is briefly discussed.
