A modified CKKW matrix element merging approach to angular-ordered parton showers
arXiv:0905.3072 · doi:10.1088/1126-6708/2009/11/038
Abstract
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 elements and parton shower and an improved description of LEP data.
