One-Loop Calculations with BlackHat
C. F. Berger, Z. Bern, L. J. Dixon +5
We describe BlackHat, an automated C++ program for calculating one-loop amplitudes, and the techniques used in its construction. These include the unitarity method and on-shell rec…
An Automated Implementation of On-Shell Methods for One-Loop Amplitudes
C. F. Berger, Z. Bern, L. J. Dixon +5
We present the first results from BlackHat, an automated C++ program for calculating one-loop amplitudes. The program implements the unitarity method and on-shell recursion to cons…
Hard QCD Processes at Colliders
Lance J. Dixon
Recent developments in the study of hard QCD processes at colliders are reviewed, in the context of the imminent startup of the LHC.
Di-photon production at the LHC
Zvi Bern, Lance Dixon, Carl Schmidt
The standard model production of two photons is one of the most important backgrounds to light Higgs boson production at the LHC. In this talk we discuss the di-photon background,…
Strings and Supersymmetry as Tools for Perturbative QCD
L. Dixon
We review techniques simplifying the analytic calculation of one-loop QCD amplitudes with many external legs, for use in next-to-leading-order corrections to multi-jet processes. W…
The Five Gluon Amplitude and One-Loop Integrals
Z. Bern, L. Dixon, D. A. Kosower
We review the conventional field theory description of the string motivated technique. This technique is applied to the one-loop five-gluon amplitude. To evaluate the amplitude a g…
