A method is detailed for the phase space integration of multi-jets cross sections at lepton colliders, applicable to parton level Monte Carlo's at any order in perturbation theory. Other non-jet objects, massless or massive, can be included in the phase space generation. We correlate the bremsstrahlung events in a manner that integrates out all partonic configurations leading to a fixed jet configuration, thereby improving convergence. This also allows the method to extend infra-red safety to…

Extending the Matrix Element Method beyond the Born approximation: calculating event weights at next-to-leading order accuracy
A bstractIn this article we illustrate how event weights for jet events can be calculated efficiently at next-to-leading order (NLO) accuracy in QCD. This is a crucial prerequisite for the…

A Forward Branching Phase-Space Generator
We develop a forward branching phase-space generator for use in next-to-leading order parton level event generators. By performing 2 → 3 branchings from a fixed jet phase-space point, all…

Finding the Higgs boson in decays to $Z \gamma$ using the matrix element method at Next-to-Leading Order
We illustrate how the Matrix Element Method at Next-to-Leading Order (MEM@NLO) can be used to discriminate between events arising from the production of a Higgs boson, which subsequently decays to a…
Kaleu: A General-Purpose Parton-Level Phase Space Generator
TLDR
Kaleu is an independent, true phase space generator, written in Fortran, such that it can independently deal with several scattering processes in parallel.
Comix, a new matrix element generator
TLDR
A new tree-level matrix element generator, based on the color dressed Berends-Giele recursive relations, is presented, dedicated to be used with large multiplicities and color sampling.
