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.
