Compatibility of a dark matter discovery at XENONnT/LZ with the WIMP thermal production mechanism

Understand

The discovery of dark matter (DM) at XENONnT or LZ would place constraints on DM particle mass and coupling constants.

• It is interesting to ask when these constraints can be compatible with the DM thermal production mechanism.
• We address this question within the most general set of renormalisable models that preserve Lorentz and gauge symmetry, and that extend the Standard Model by one DM candidate of mass $m_{\rm DM}$ and one particle of mass $M_{med}$ mediating DM-quark interactions.
• Our analysis divides into two parts.
