Non-Abelian gauge lepton symmetry as the gateway to dark matter

Following a previous proposal, lepton number is considered as the result of a spontaneously broken non-Abelian gauge SU(2)(N) symmetry. New fermions are added to support this new symmetry, the spontaneous breaking of which allows these new fermions to be part of the dark sector, together with the vector gauge boson which communicates between them and the usual leptons. A byproduct is a potential significant contribution to the muon anomalous magnetic moment. (C) 2021 The Author(s). Published by Elsevier B.V.

According to the proposal, lepton number is considered as the result of a spontaneously broken non-Abelian gauge SU(2)(N) symmetry. New fermions are added to support this new symmetry, with their spontaneous breaking allowing them to be part of the dark sector, potentially contributing significantly to the muon anomalous magnetic moment.
