Comparative study of various algorithms for the merging of parton showers and matrix elements in hadronic collisions
نویسندگان
چکیده
We compare different procedures for combining fixed-order tree-level matrixelement generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW and MLM schemes using different matrix-element generators and different parton cascades. We find that although similar results are obtained in all cases, there are important differences.

Implementing the ME+PS merging algorithm
The method to merge matrix elements for multi particle production and parton showers in e+e− annihilations and hadronic collisions and its implementation into the new event generator SHERPA is described in detail. Examples highlighting different aspects of it are thoroughly discussed, some results for various cases are presented. In addition, a way to extend this method to general electroweak i...
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 کاملExtending CKKW-merging to One-Loop Matrix Elements
We extend earlier schemes for merging tree-level matrix elements with parton showers to include also merging with one-loop matrix elements. In this paper we make a first study on how to include one-loop corrections, not only for events with a given jet multiplicity, but simultaneously for several different jet multiplicities. Results are presented for the simplest non-trivial case of hadronic e...
متن کاملA modified CKKW matrix element merging approach to angular-ordered parton showers
A modified version of the CKKW matrix element merging algorithm is presented, suitable for use in an angular-ordered parton shower, using truncated showers and forced splittings. The algorithm is implemented in the Herwig++ Monte Carlo event generator for the benchmark process e+e− → hadrons. Results are presented at parton and hadron levels, demonstrating a smooth merging between the matrix el...
متن کاملQCD 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...
