Resum

The new event generation framework SHERPA, i.e.\ Simulation for High 
Energy Reactions of PArticles, will be presented. As the well established 
tools Pythia and Herwig, it aims at a full simulation of events at current 
and future high energy experiments. In its current form SHERPA is able to 
provide hadron level predictions for e.g.\ $e^+e^-$, $pp$ or $p(\bar p)$ 
collisions. Owing to the fact that SHERPA has its own matrix element 
generator, more tree-level processes, for instance SUSY particle 
productions, can be studied on the signal level. The capabilities of 
SHERPA shall be demonstrated by showing a selection of results. One of the 
striking features of SHERPA is the inclusion of the CKKW prescription to 
combine tree level multijet matrix elements with the subsequent parton 
showers. On that score recent results related to the production of weak 
vector bosons in association with jets at the Tevatron and the LHC will be 
discussed.
