Description
We consider the case that dark matter (DM) is solely composed of se lf-conjugate (Majorana) particle interacting with ordinary standard model (SM) matter exclusively through so-called U(1) hypercharge anapole terms. Based on the general three-point vertices of a virtual photon $\gamma$ and a massive gauge boson $Z$ and two identical on-shell particles of any spin $J$ and mass $m$, we evaluate the relic abundance and the direct detection cross sections. Combining the constraints from these experiments and those from the high-energy Large Hadron Collider (LHC) experiments, we perform a systematic investigation of whether the limits on the mass and coupling strengthes depend on the spin of the anapole DM.
