The GoSam package: an overview
  The public code GOSAM for the computation of the one loop virtual corrections to scattering amplitudes in the Standard Model and beyond is presented. Particular emphasis is devoted to the interface with other public tools via the Binoth Les Houches Accord. We show with examples that doing LHC phenomenology including automatically Next to Leading Order QCD corrections is now handy.
