Query: Characterizing dark matter at the LHC in Drell-Yan events   Spectral features in LHC dileptonic events may signal radiative corrections
coming from new degrees of freedom, notably dark matter and mediators. Using
simplified models, we show how these features can reveal the fundamental
properties of the dark sector, such as self-conjugation, spin and mass of dark
matter, and the quantum numbers of the mediator. Distributions of both the
invariant mass $m_{\ell \ell}$ and the Collins-Soper scattering angle
$cos\theta_{CS}$ are studied to pinpoint these properties. We derive
constraints on the models from LHC measurements of $m_{\ell \ell}$ and
$cos\theta_{CS}$, which are competitive with direct detection and jets +
Missing Energy searches. We find that in certain scenarios the $cos\theta_{CS}$
spectrum provides the strongest bounds, underlying the importance of scattering
angle measurements for non-resonant new physics.
