In this publication the implementation of a new parton shower model based on the Catani-Seymour dipole factorisation, as first suggested by [1,2], is discussed. First results obtained with the new algorithm are compared with experimental data. 1steffen@theory.phy.tu-dresden.de 2frank.krauss@durham.ac.uk

A standard file format is proposed to store process and event information, primarily output from parton-level event generators for further use by general-purpose ones. The information content is identical with what was already defined by the Les Houches Accord five years ago, but then in terms of Fortran commonblocks. This information is embedded in a… (More)

In this paper the Yennie–Frautschi–Suura approach is used to simulate real and virtual QED corrections in particle decays. It makes use of the universal structure of soft photon corrections to resum the leading logarithmic QED corrections to all orders, and it allows a systematic correction of this approximate result to exact fixed order results from… (More)

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… (More)

This paper reports on a case study that examined the process of designing and evaluating a learning object to help students understand the therapeutic principles of drug administration. The challenges and issues associated with creating learning objects using interactive multimedia software will be described. The study had two broad objectives: (1) to… (More)

The new version of the parton shower module APACIC++ for the SHERPA event generator framework is presented. It incorporates some features, that are specific for the consistent merging with multi-particle matrix elements at tree-level. This publication also includes some exemplary results and a short description of the upgraded class structure of APACIC++,… (More)

I review progress on investigations concerning top quark physics and QCD at a future linear e+e collider that has been achieved since the presentation of the TESLA technical design report [1] in spring 2001. I concentrate on studies that have been presented during the workshop series of the Extended Joint ECFA/DESY Study on Physics and Detectors for a… (More)

Triple gauge boson hadroproduction, in particular the production of three W-bosons at the LHC, is considered at next-to leading order accuracy in QCD. The NLO matrix elements are combined with parton showers. Multijet merging is invoked such that NLO matrix elements with one additional jet are also included. The studies here incorporate both the signal and… (More)

High-energy particle collisions are a research field of major interest. The search for new physics at present and future accelerators, like Tevatron at Fermilab, the Large Hadron Collider at Cern and a new linear electronpositron-machine, represents a challenge both for theorists as well as for experimentalists. In order to compare theoretical predictions… (More)

Hadron colliders, such as the Tevatron at Fermilab or the Large Hadron Collider (LHC), which is under construction at CERN, provide an excellent opportunity to test whether the observed dynamics of collision products coincide with the predictions made by the Standard Model and its possible extensions. In such an environment, the accurate description of QCD… (More)
