Variants of the Dark Left-Right Gauge Model: Neutrinos and Scotinos
Abstract
In the recently proposed dark left-right gauge model (DLRM) of particle interactions, the usual left-handed lepton doublet (nu,e)L transforming under SU(2)L is accompanied by the UNUSUAL right-handed fermion doublet (n,e)R transforming under SU(2)R, where nR is NOT the Dirac mass partner of nuL. In this scenario, whereas nuL is certainly a neutrino, nR should be considered a SCOTINO, i.e. a dark-matter fermion. Variants of this basic idea are discussed, including its minimal SCOTOGENIC realization.
