  Precise theoretical predictions are vital for the interpretation of Standard
Model measurements and facilitate conclusive searches for New Physics phenomena
at the LHC. In this contribution I highlight some of the ongoing efforts in the
framework of the Sherpa event generator to provide accurate and realistic
simulations of Standard Model production processes. This includes the automated
evaluation of NLO QCD and NLO EW corrections and their consistent consideration
in the parton-shower evolution of scattering events. Particular emphasis is
given to examples and applications involving the production of top quarks.
