Description

Direct detection experiments search for nuclear recoil events induced by the non- relativistic scattering of Milky Way dark matter (DM) particles in low-background detectors. Current strategies for the experimental analysis and theory interpretation of direct detection experiments focus on two parameters: the DM particle mass, and the cross-section for DM-nucleon scattering computed under the assumption of spin- independent or spin-dependent DM-nucleon interactions. In this framework, the DM particle spin remains unconstrained. In my talk, I introduce two new analysis strategies relying on the most general classification of single mediator models for DM- quark interaction. A first strategy potentially allows to extract the DM particle spin in the presence of a signal at direct detection experiments with directional sensitivity. A second strategy shows that a signal at XENONnT together with the detection, or lack of detection, of a mono-jet signal at the LHC Run 3 would significantly narrow the range of possible DM interactions and spins. This work is performed within the Swedish consortium for Dark matter Direct Detection (SweDCube), which links theoretical groups at the Chalmers University of Technology with the experimental group in XENON at the Stockholm University. SweDCube's goals and mission will also be reviewed in the talk.
