Towards an automation of EW NLO corrections with Sherpa and Recola — •Stephan Bräuer and Steffen Schumann — II. Physikalisches Institut, Georg-August-Universität Göttingen

In order to keep up with the ever increasing experimental precision, higher-order perturbative corrections need to be considered in corresponding theoretical predictions.

This talk provides an overview over the recent developments in the automation of electroweak next-to-leading order correction with the Monte Carlo event generator Sherpa and the one-loop generator Recola. We report on the implementation and validation of an interface to access Recola loop amplitudes from the Sherpa framework for carrying out next-to-leading order QCD and EW computations. Furthermore, first results for NLO QCD+EW calculations with Sherpa+Recola are shown and the remaining challenges for fully automated calculations of NLO EW corrections are outlined.
