Four-Jet Production at the Large Hadron Collider at Next-to-Leading Order in QCD

Understand

We present the cross sections for production of up to four jets at the Large Hadron Collider, at next-to-leading order in the QCD coupling.

• We use the BlackHat library in conjunction with SHERPA and a recently developed algorithm for assembling primitive amplitudes into color-dressed amplitudes.
• We adopt the cuts used by ATLAS in their study of multi-jet events in pp collisions at \sqrt{s} = 7 TeV.
• We include estimates of nonperturbative corrections and compare to ATLAS data.
