A largely model-independent way to search for dark matter at the LHC is
to look for particles that do not interact with the detector and thereby
create an imbalance in the observed momentum. However, to interpret such
searches one needs reliable predictions for the Standard Model processes
with the same signature.

I review a recent ATLAS measurement, with a focus on observables where
one has to go beyond the standard theory paradigm of combining fixed-
order perturbation theory with a parton shower. I show that adding high-
energy resummation leads to much better agreement between theory and data.
