Generalized Unitarity and Six-Dimensional Helicity
Zvi Bern, John Joseph Carrasco, Tristan Dennen +2
We combine the unitarity method with the six-dimensional helicity formalism of Cheung and O'Connell to construct loop-level scattering amplitudes. As a first example, we construct…
Precise Predictions for W + 4 Jet Production at the Large Hadron Collider
C. F. Berger, Z. Bern, L. J. Dixon +6
We present the first next-to-leading order QCD results for W + 4-jet production at hadron colliders. Total cross sections, as well as distributions in the jet transverse momenta an…
Vector Boson + Jets with BlackHat and Sherpa
C. F. Berger, Z. Bern, L. J. Dixon +6
We review recent NLO QCD results for W,Z + 3-jet production at hadron colliders, computed using BlackHat and SHERPA. We also include some new results for Z + 3-jet production at th…
Next-to-Leading Order QCD Predictions for Z,gamma^*+3-Jet Distributions at the Tevatron
C. F. Berger, Z. Bern, L. J. Dixon +6
Using BlackHat in conjunction with SHERPA, we have computed next-to-leading order QCD predictions for a variety of distributions in Z,gamma*+1,2,3-jet production at the Tevatron, w…
