Abstract
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 multijet events in pp collisions at √s=7 TeV. We include estimates of nonperturbative corrections and compare to ATLAS data. We store intermediate results in a framework that allows the inexpensive computation of additional results for different choices of scale or parton distributions.
Highlights
We present the cross sections for production of up to four jets at the Large Hadron Collider, at next-to-leading order in the quantum chromodynamics (QCD) coupling
O U Pure-jet events are abundant at the Large Hadron ColC lider (LHC), providing a window onto new strongly interB acting physics [1]
IE T leading order (LO) contribution in the QCD coupling, S αs, does not suffice for quantitatively precise predictions, V I which require at least next-to-leading-order (NLO) accuracy in the QCD coupling
Summary
Four-Jet Production at the Large Hadron Collider at Next-to-Leading Order in QCD 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. In this Letter, we provide NLO QCD predictions R for the production of up to four jets, and compare them to ATLAS data.
