Majoron emitting neutrinoless double beta decay in the electroweak chiral gauge extensions
F. Pisano, S. Shelly Sharma
Abstract
Fundamental mechanisms for Majoron emitting neutrinoless double beta decay in SU(3)C x GW x U(1) models, for electroweak flavor chiral extensions, GW = SU(3)L and SU(4)L are pointed out. Both kinds of known Majoron emitting processes, charged Majoron emitting where the massless Nambu-Goldstone boson itself carries lepton charge, L=-2, and the ordinary Majoron emitting where the boson has a small mass are found possible. PACS numbers: 11.15.Ex, 12.60.Fr, 14.80.Cp
