Improved parton showers at large transverse momenta

Corke, Richard LU and Sjöstrand, Torbjörn LU orcid (2010) In European Physical Journal C. Particles and Fields 69(1-2). p.1-18
Abstract
Several methods to improve the parton-shower description of hard processes by an injection of matrix-element-based information have been presented over the years. In this article we study (re)weighting schemes for the first/hardest emission. One objective is to provide a consistent matching of the POWHEG next-to-leading order generator to the Pythia shower algorithms. Another is to correct the default behaviour of these showers at large transverse momenta, based on a comparison with real-emission matrix elements.
