Sterile neutrinos coupling only to third-generation fermions are attractive dark matter candidates. In an EFT approach we demonstrate that they can generate the observed relic density without violating constraints from direct and indirect detection. Such an EFT represents a gauged third-generation $B-L$ model, as well as third-generation scalar or vector leptoquarks. LHC measurements naturally distinguish the different underlying models.

黑暗物质EFT，第三部-中微子WIMP

仅耦合至第三代费米子的无菌中微子是有吸引力的暗物质候选物。在EFT方法中，我们证明了它们可以产生观察到的文物密度，而不会违反直接和间接检测的约束。这样的EFT代表了规范的第三代$ BL $模型，以及第三代标量或矢量钩针夸克。LHC测量自然可以区分不同的基础模型。
