Matching NLO QCD with parton shower in Monte Carlo scheme - the KrkNLO method
read the original abstract
A new method of including the complete NLO QCD corrections to hard processes in the LO parton-shower Monte Carlo (PSMC) is presented. This method, called KrkNLO, requires the use of parton distribution functions in a dedicated Monte Carlo factorization scheme, which is also discussed in this paper. In the future, it may simplify introduction of the NNLO corrections to hard processes and the NLO corrections to PSMC. Details of the method and numerical examples of its practical implementation, as well as comparisons with other calculations, such as MCFM, MC@NLO, POWHEG, for single $Z/\gamma^*$-boson production at the LHC, are presented.

MAcNLOPS for ZZ Pair Production at the LHC
MAcNLOPS is implemented for ZZ production at the LHC, eliminating negative H weights via a shower veto on S events while agreeing with MC@NLO except for small low-pT effects.
