oai:localhost:PNK-19612022-08-17T05:54:45Z Canonical seesaw implication for two-component dark matter Phung Van Dong Cao H. Nam Duong Van Loi Q1 We show that the canonical seesaw mechanism implemented by the U ( 1 ) B − L gauge symmetry provides two-component dark matter naturally. The seesaw scale that breaks B − L defines a residual gauge symmetry to be Z 6 = Z 2 ⊗ Z 3 , where Z 2 leads to the usual matter parity, while Z 3 is newly recognized, transforming quark fields nontrivially. The dark matter components—that transform nontrivially under the matter parity and Z 3 , respectively—can gain arbitrary masses, despite the fact that the Z 3 dark matter may be heavier than the light quarks u , d . This dark matter setup can address the XENON1T anomaly recently observed and other observables, given that the dark matter masses are nearly degenerate, heavier than the electron and the B − L gauge boson Z ′ , as well as the fast-moving Z 3 dark matter has a large B − L charge, while the Z ′ is viably below the beam dump experiment sensitive regime. 2021-07-06T03:20:54Z 2021-07-06T03:20:54Z 2021 Article https://journals.aps.org/prd/abstract/10.1103/PhysRevD.103.095016 https://dlib.phenikaa-uni.edu.vn/handle/PNK/1961 https://doi.org/10.1103/PhysRevD.103.095016 en application/pdf Phys.
