Effective Bounds on Asymmetric Dark Matter

In this talk, I will present an updated assessment of constraints on dark matter (DM) interactions from collider experiments and their implications for asymmetric dark matter (ADM). We model ADM as a Dirac fermion that primarily interacts with Standard Model fermions. Using an effective field theory approach, we derive bounds from mono-jet searches at the Large Hadron Collider (LHC) and mono-photon searches at the Large Electron-Positron Collider (LEP). By combining collider searches with limits from direct detection and other observational probes, we provide a comprehensive overview of the viability of different ADM interactions. I will also discuss the potential of the Future Circular Collider for electron-positron collisions (FCC-ee) to probe the currently unconstrained regions.
