Multi-jet Merging with NLO Matrix Elements
Siegert, F.
In the algorithm presented here, the ME PS approach to merge samples of tree-level matrix elements into inclusive event samples is combined with the POWHEG method, which includes
exact next-to-leading order matrix elements in the parton shower. The advantages of the method are discussed and the quality of its implementation in SHERPA is exemplified by results for e+e- annihilation into hadrons at LEP, for deep-inelastic lepton-nucleon scattering at HERA, for Drell-Yan lepton-pair production at t...

In the algorithm presented here, the ME PS approach to merge samples of tree-level matrix elements into inclusive event samples is combined with the POWHEG method, which includes
exact next-to-leading order matrix elements in the parton shower. The advantages of the method are discussed and the quality of its implementation in SHERPA is exemplified by results for e+e- annihilation into hadrons at LEP, for deep-inelastic lepton-nucleon scattering at HERA, for Drell-Yan lepton-pair production at the Tevatron and for W+W- production at LHC energies.
