Description
Spectral features in LHC dileptonic events may signal radiative corrections from dark matter and mediators. It is shown using simplified models how these features may reveal the fundamental properties of the dark sector, such as the self-conjugation, spin and mass of DM, and the quantum numbers of the mediator. Distributions of both the invariant mass mll and the Collins-Soper scattering angle cos\theta are studied to pinpoint these properties. Constraints on the models are derived from LHC measurements of mll and cos\theta, which are competitive with direct detection and jets + MET searches.
