Parallel session talk Top and Electroweak Physics T07: Top and Electroweak Physics


Manfred Kraus (Florida State University)


We will present our recent calculation of matching NLO QCD corrections
to the production of a top-quark pair in association with a W boson
using the POWHEG-BOX framework. We compare our results with other
Monte Carlo generators for the two same-sign lepton signature
commonly used by the experiments. Special focus will be put on the
assessment of the importance of subleading electroweak contributions
in the modelling of the production process. In addition, We will discuss
theoretical uncertainties of our predictions, which are estimated by
variations of the renormalization and factorization scales, also
matching uncertainties are estimated.
