Matching the Nagy-Soper parton shower at next-to-leading order — •Manfred Kraus — Institute for Theoretical Particle Physics and Cosmology, RWTH Aachen University

We give a short review of the shower concept, first introduced by Nagy and Soper, that includes full quantum correlations in the shower evolution. We also state the current status of implementation of the publicly available shower program Deductor. However, the main focus of the talk will be the matching of the shower at next-to-leading order within the MC@NLO formalism. Matching is necessary in order to increase the accuracy of theoretical predictions and to employ a hadronization model. We will show first results using Deductor in conjunction with the Helac-NLO framework for top quark pair production in association with one hard jet.
