One-Loop Multi-Parton Amplitudes with a Vector Boson for the LHC
C. F. Berger, Z. Bern, L. J. Dixon +5
In this talk, we present the first, numerically stable, results for the one-loop amplitudes needed for computing W,Z + 3 jet cross sections at the LHC to next-to-leading order in t…
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…
Direct extraction of one-loop integral coefficients
Darren Forde
We present a general procedure for obtaining the coefficients of the scalar bubble and triangle integral functions of one-loop amplitudes. Coefficients are extracted by considering…
