Traditionally, matrix elements have been used to provide the probability for multijet
configurations in e+ e− annihilation events. Some serious discrepancies between …

Several methods to improve the parton-shower description of hard processes by an injection
of matrix-element-based information have been presented over the years. In this article we …

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 structure of events in high-energy collisions is complex and not predictable from first
principles. Event generators allow the problem to be subdivided into more manageable …

We propose a method for combining QCD matrix elements and parton showers in Monte
Carlo simulations of hadronic final states in e+e− annihilation. The matrix element and …

Monte Carlo event generators are essential components of almost all experimental analyses
and are also widely used by theorists and experiments to make predictions and preparations …

We present a new algorithm for the probalistic evolution of jet cascades, based on the
leading log approximation to perturbative QCD, augmented by coherence studies …

Abstract General-purpose Monte Carlo event generators have become important tools in
particle physics, allowing the simulation of exclusive hadronic final states. In this article we …

A bstract Parton shower Monte Carlo event generators in which the shower evolves from
hard splittings to soft splittings generally use the leading color (LC) approximation, which is …

Multihadronic e+ e− annihilation events at a center-of-mass energy of 29 GeV have been
studied with both the original (PEP 5) Mark II and the upgraded Mark II detectors. Detector …
