Recasting direct detection limits within micrOMEGAs and implication for non-standard Dark Matter scenarios

Understand

Direct detection experiments obtain 90% upper limits on the elastic scattering cross sections of dark matter with nucleons assuming point-like interactions and standard astrophysical and cosmological parameters.

• In this paper we provide a recasting of the limits from XENON1T, PICO-60, CRESST-III and DarkSide-50 and include them in micrOMEGAs.
• The code can then be used to directly impose constraints from these experiments on generic dark matter models under different assumptions about the DM velocity distribution or on the nucleus form factors.
• Moreover new limits on the elastic scattering cross sections can be obtained in the presence of a light t-channel mediator or of millicharged particles.
