Abstract

Next-to-leading order (NLO) electroweak corrections will play an important role in Run 2 of the Large Hadron Collider (LHC). Even though they are typically moderate at the level of total cross sections, they can lead to substantial deviations in the shapes of distributions. In particular, for the search for new physics, but also for a precise determination of Standard Model observables, their inclusion in theoretical predictions is mandatory for a reliable estimation of the Standard Model contribution. In this article we review the status and recent developments in electroweak calculations and their automation for LHC processes. We discuss general issues and properties of NLO electroweak corrections and present some examples, including the full calculation of the NLO corrections to the production of a W -boson in association with two jets computed using GoSam interfaced to MadDipole .
