Stabilizing the invisible axion in 3-3-1 models

arXiv:hep-ph/0308037 · doi:10.1103/PhysRevD.69.077702

Abstract

By introducing local symmetries with in two 3-3-1 models, it is possible to implement an automatic Peccei-Quinn symmetry, keeping the axion protected against gravitational effects at the same time. Both models have a domain wall problem and the neutrinos are strictly Dirac particles.
