Manfred Kraus
TL;DR
This paper presents a comparison of the Nagy-Soper parton shower matched with NLO QCD calculations to other schemes, demonstrating its effectiveness in simulating top quark pair production with a jet at the LHC.
Contribution
It introduces the Nagy-Soper parton shower with an MC@NLO-like matching scheme and compares its performance with other methods using the HELAC-NLO framework.
Findings
Nagy-Soper shower provides competitive results for top pair production with jets.
The matching scheme effectively combines NLO calculations with the parton shower.
Results are consistent with other schemes across various observables.
Abstract
We briefly summarize the Nagy-Soper parton shower and the MC@NLO-like matching scheme. Results obtained using HELAC-NLO framework in conjunction with DEDUCTOR for top quark pair production in association with one hard jet at the LHC are presented. A comparison of our results with other matching schemes and other parton showers is also discussed for various observables.
