Full one-loop amplitudes from tree amplitudes
We establish an efficient polynomial-complexity algorithm for one-loop calculations, based on generalized D-dimensional unitarity. It allows automated computations of both cut-constructible and
A Simple shower and matching algorithm
We present a simple formalism for parton-shower Markov chains. As a first step towards more complete ''uncertainty bands,'' we incorporate a comprehensive exploration of the ambiguities inherent in
Generic User Process Interface for Event Generators
Generic Fortran common blocks are presented for use by High Energy Physics event generators for the transfer of event configurations from parton level generators to showering and hadronization event
A multi-threaded version of MCFM
Modifying MCFM using OpenMP to implement multi-threading and modifying the integration routine VEGAS to distribute the event evaluation over the threads, while combining all events at the end of every iteration to optimize the numerical integration.
Higgs boson production in association with a jet at NNLO using jettiness subtraction
We use the recently proposed jettiness-subtraction scheme to provide the complete calculation of Higgs boson production in association with a jet in hadronic collisions through
Z-Boson Production in Association with a Jet at Next-To-Next-To-Leading Order in Perturbative QCD.
We present the first complete calculation of Z-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order in perturbative QCD. Our computation uses the
A numerical unitarity formalism for evaluating one-loop amplitudes
Recent progress in unitarity techniques for one-loop scattering amplitudes makes a numerical implementation of this method possible. We present a 4-dimensional unitarity method for calculating the
