Universality in W+Multijet Production
Z. Bern, L. J. Dixon, F. Febres Cordero +5
We study -boson production accompanied by multiple jets at 7 TeV at the LHC. We study the jet-production ratio, of total cross sections for +- to +()-jet productio…
High multiplicity processes with BlackHat and Sherpa
Jeppe R. Andersen, Stephanie Bartle, Zvi Bern +7
In this contribution, we present an intermediate storage format for next-to-leading order (NLO) events and explain the advantages of presenting a NLO calculation in this format. We…
High multiplicity W+jets predictions at NLO
Z. Bern, L. J. Dixon, F. Febres Cordero +5
In these proceedings we present results from a recent calculation for the production of a W boson in conjunction with five jets at next-to-leading order in perturbative QCD. We als…
Next-to-Leading Order W + 5-Jet Production at the LHC
Z. Bern, L. J. Dixon, F. Febres Cordero +5
We present next-to-leading order QCD predictions for the total cross section and for a comprehensive set of transverse-momentum distributions in W + 5-jet production at the Large H…

Zvi Bern, Kemal Ozeren, Lance J. Dixon +5
In this contribution we review recent progress with fixed-order QCD predictions for the production of a vector boson in association with jets at hadron colliders, using the program…
Missing Energy and Jets for Supersymmetry Searches
Z. Bern, G. Diana, L. J. Dixon +6
We extend our investigation of backgrounds to new physics signals, following CMS's data-driven search for supersymmetry at the LHC. The aim is to use different sets of cuts in gamm…

Z. Bern, G. Diana, L. J. Dixon +6
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 conjuncti…
Colour Decompositions of Multi-quark One-loop QCD Amplitudes
Harald Ita, Kemal Ozeren
We describe the decomposition of one-loop QCD amplitudes in terms of colour-ordered building blocks. We give new expressions for the coefficients of QCD colour structures in terms…
Driving Missing Data at Next-to-Leading Order
Z. Bern, G. Diana, L. J. Dixon +6
The prediction of backgrounds to new physics signals in topologies with large missing transverse energy and jets is important to new physics searches at the LHC. Following a CMS st…
Left-Handed W Bosons at the LHC
Z. Bern, G. Diana, L. J. Dixon +8
The production of W bosons in association with jets is an important background to new physics at the LHC. Events in which the W carries large transverse momentum and decays leptoni…
