Left-Right Symmetric Theory with Light Sterile Neutrinos

Understand

A simple theoretical framework for the spontaneous breaking of parity, baryon and lepton numbers is proposed.

• In this context, the baryon and lepton numbers are independent local gauge symmetries, while parity is defined making use of the left-right symmetry.
• We show that in the minimal model the new leptoquark fields needed to define an anomaly-free theory also generate neutrino masses through the type III seesaw mechanism.
• The spectrum of neutrinos and some phenomenological aspects are discussed.
