Scotoseesaw model implied by dark right-handed neutrinos

Tóm tắt

We find a dark gauge symmetry U(1)D that transforms nontrivially only for three right-handed neutrinos, ν1,2,3R. The anomaly cancellation demands that they have a dark charge D=0,1,+1 assigned to ν1,2,3R, respectively. The dark charge is broken by two units down to a dark parity, i.e., U(1)DPD=(1)D, which stabilizes a dark matter candidate. Interestingly, the model manifestly supplies neutrino masses via joint seesaw and scotogenic mechanisms, called scotoseesaw. Published by the American Physical Society 2024
