Simulating W/Z+jets production at the CERN LHC
Frank Krauss, Andreas Schaelicke, Steffen Schumann, Gerhard Soff
Abstract
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.
