“…In the following we display some illustrative results, comparing the performance of APACIC++ with the standard event generators HERWIG [22], PYTHIA [23], ARIADNE [24] and with data taken by the DELPHI collaboration. The parameters of HERWIG, PYTHIA and ARIADNE were tuned in refs.…”

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 parton shower domains are separated at some value y ini of the jet resolution, defined according to the k T -clustering algorithm. The matrix elements are modified by Sudakov form factors and the parton showers are subjected to a veto procedure to cancel dependence on y ini to next-to-leading logarithmic accuracy. The method provides a leading-order description of hard multi-jet configurations together with jet fragmentation, while avoiding the most serious problems of double counting. We present first results of an approximate implementation using the event generator APACIC++.

“…CC DIS events are simulated using the DJANGO [18] generator, which includes first order leptonic QED radiative corrections based on HERACLES [19]. The production of two or more jets in DJANGO is accounted for using the colour-dipole model [20]. The RAPGAP [21] event generator, which implements the Born, QCD Compton and Boson Gluon Fusion matrix elements, is used to model NC DIS events.…”

A search for single top quark production is performed in the full e ± p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb −1 . Decays of top quarks into a b quark and a W boson with subsequent leptonic or hadronic decay of the W are investigated. A multivariate analysis is performed to discriminate top quark production from Standard Model background processes. An upper limit on the top quark production cross section via flavour changing neutral current processes σ(ep → etX) < 0.25 pb is established at 95% CL. Limits on the anomalous coupling κ tuγ are derived.Accepted by Phys. Lett. B

“…Version 6.3 [7] offers as an alternative the possibility to order the shower according to the transverse momentum of the radiated parton with respect to the emitter's direction (see [8] for more discussion on the transverse momentum definition), which yields a better implementation of angular ordering [8]. We would like to point out that the ARI-ADNE Monte Carlo generator [17] has the correct large-angle soft gluon evolution pattern, which generates the non-global single logarithms in the large-N c limit. Since however the most commonly used and popular programs are the ones we mentioned before, we shall be interested in comparisons to the showers therein.…”

We study the mismatch between a full calculation of non-global singlelogarithms in the large-N c limit and an approximation based on free azimuthal averaging, and the consequent angular-ordered pattern of soft gluon radiation in QCD. We compare the results obtained in either case to those obtained from the parton showers in the Monte Carlo event generators HERWIG and PYTHIA, with the aim of assessing the accuracy of the parton showers with regard to such observables where angular ordering is merely an approximation even at leading-logarithmic accuracy and which are commonly employed for the tuning of event generators to data.
