Abstract

10 pp. (1993)., A new jet clustering algorithm-Arclus-is presented. The main difference between this and conventional algorithms is that while the latter in each step join two clusters into one,Arclus joins three clusters into two. The performance ofArclus in terms of the size of hadronization corrections is studied for some jet-reconstruction tasks ine+e− andep collisions, and is found to be as good as or, for some tasks inep collisions, better than conventional clustering algorithms.

Abstract

24 pp. (1991)., We have measured the cross section and $Q^2$-dependence of the reaction γγ→ multihadrons, using the CELLO detector at DESY, for visible final-state masses between 4 and 9 GeV. The data are well fitted by an incoherent sum of Generalised Vector Meson Dominance and Quark Parton Model terms, but at lowQ2 require the addition of a third component which resembles the QPM but is less two-jet-like. With and without this term, the GVDM cross section atQ2=0 is found to be 200±20 and 250±25 nb, respectively.

Abstract

27 pp. (1988)., We discuss jet reconstruction methods with respect to their suitability forep collisions at HERA and study the expected properties of such jets. The results are based on complete event simulation using current models of jet evolution and hadronization in combination with experimentally tested jet algorithms. The effects of calorimeter resolution are illustrated by explicit simulation of the energy profile and fluctuations in a simplified, but realistic detector.

Abstract

26 pp. (1988)., The production of heavy flavours inep collisions at the HERA energy is studied using a model based on boson-gluon fusion into a heavy quark-antiquark pair followed by gluon emission and string hadronization. Total cross-sections and dependence on basic kinematical variables are given as well as distributions of the most important variables at both the quark and hadron level, e.g. rapidity and transverse momentum. Charm, bottom and top production is compared and signatures for their separation are discussed in terms of decay muons and global event shape properties.
