    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 oth...
