Query: pp -> ttj + X matched to the Nagy-Soper parton shower at NLO QCD   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.
