The Dark Penguin Shines Light at Colliders

Understand

Collider experiments are one of the most promising ways to constrain Dark Matter (DM) interactions.

• For several types of DM-Standard Model couplings, a meaningful interpretation of the results requires to go beyond effective field theory, considering simplified models with light mediators.
• This is especially important in the case of loop-mediated interactions.
• In this paper we perform the first simplified model study of the magnetic dipole interacting DM, by including the one-loop momentum-dependent form factors that mediate the coupling -- given by the Dark Penguin -- in collider processes.
