QCD effects in mono-jet searches for dark matter

Haisch, Ulrich, Kahlhoefer, Felix, Re, Emanuele

Understand

LHC searches for missing transverse energy in association with a jet allow to place strong bounds on the interactions between dark matter and quarks.

In this article, we present an extension of the POWHEG BOX capable of calculating the underlying cross sections at the next-to-leading order level.
This approach enables us to consistently include the effects of parton showering and to apply realistic experimental cuts.
We find significant differences from a fixed-order analysis that neglects parton showering effects.
