Summary: | JHEP 05 (2020) 090 We argue that neutrino mass and dark matter can arise from an approximate
$B-L$ symmetry. This idea can be realized in a minimal setup of the flipped
3-3-1 model, which discriminates lepton families while keeping universal quark
families and uses only two scalar triplets in order for symmetry breaking and
mass generation. This proposal contains naturally an approximate non-Abelian
$B-L$ symmetry which consequently leads to an approximate matter parity. The
approximate symmetries produce small neutrino masses in terms of type II and
III seesaws and may make dark matter long lived. Additionally, dark matter
candidate is either unified with the Higgs doublet by gauge symmetry or acted
as an inert multiplet. The Peccei-Quinn symmetry is discussed. The gauge and
scalar sectors are exactly diagonalized. The signals of the new physics at
colliders are examined. |
