Improved Partonic Event Generators at Lepton Colliders
@article{Giele2015ImprovedPE, title={Improved Partonic Event Generators at Lepton Colliders}, author={Walter T. Giele}, journal={arXiv: High Energy Physics - Phenomenology}, year={2015} }
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…
