  The merging procedure of tree-level matrix elements and the subsequent parton
shower as implemented in the new event generator SHERPA will be validated for
the example of single gauge boson production at the LHC. The validation
includes consistency checks and comparisons to results obtained from other
event generators. In particular, comparisons with full next-to-leading order
QCD calculations prove SHERPA's ability to correctly account for additional
hard QCD radiation present in these processes.
