Description
One of the cleanest channels to look for New Physics at the LHC is the neutral-current Drell Yan process. While there's an ongoing search for new resonance states (Z' models) in this channel, it is also important to probe the effects of hidden sector TeV-scale states running in loop amplitudes that interfere with the Standard Model process. To this end, I will motivate an effective theory with a hidden sector that provides a dark matter candidate, and discuss the role of dispersion relations in producing our signals on the Drell-Yan process. I will conclude with constraints from the dark matter relic abundance, and direct detection and collider experiments.
