QCD matrix elements + parton showers
We propose a method for combining QCD matrix elements and parton showers in Monte Carlo simulations of hadronic final states in ee annihilation. The matrix element and parton shower domains are separated at some value yini of the jet resolution, defined according to the kT -clustering algorithm. The matrix elements are modified by Sudakov form factors and the parton showers are subjected to a v...
متن کاملMatching Parton Showers and Matrix Elements
We compare different procedures for combining fixed-order tree-level matrix element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the socalled CKKW scheme and one based on the so-called MLM scheme using different matrix element generators and different parton cascades. We find that although similar results are...
متن کاملQCD matrix elements and truncated showers
We derive an improved prescription for the merging of matrix elements with parton showers, extending the CKKW approach. A flavour-dependent phase space separation criterion is proposed. We show that this new method preserves the logarithmic accuracy of the shower, and that the original proposal can be derived from it. One of the main requirements for the method is a truncated shower algorithm. ...
متن کاملMerging Parton Showers and Matrix Elements
This thesis considers models for describing high energy particle collisions. Existing phenomonological models are modified and new implementations made in order to achive a better description of states with several hard jets. To predict final state hadrons, parton showers are used together with pheonomenological hadronization models. These models describe a wide range of observables, but have t...
متن کاملCombining Qcd Matrix Elements and Parton Showers
A new method for combining QCD matrix elements and parton showers in Monte Carlo simulations of hadronic final states is outlined. The aim is to provide at least a leading-order description of all hard multi-jet configurations together with jet fragmentation to next-to-leading logarithmic accuracy, while avoiding the most serious problems of double counting.
