Towards A Direct Detection of the Spin of Dark Matter
arXiv:2212.07442 · doi:10.1016/j.physletb.2023.137956
Abstract
We investigate the contribution of higher spin particles in the signal of direct detection experiments searching for dark matter. We consider a bosonic or fermionic higher spin dark matter (HSDM) candidate which interacts with the Standard Model via a dark U(1) mediator. For a particular subclass of interactions, spin-polarized targets may be used for spin determination: The angular dependence of scatterings can distinguish integer (spin-) vs. half-integer (spin-), while the recoil energy dependence of the signal determines . We consider also the signal of a supersymmetric higher spin dark sector, which suggests a characteristic signal (''SUSY Rilles'') for directional direct detection.
