[en] Although the topic of spin was organized as a separate session in this workshop, it clearly permeates almost all areas of physics discussed. Spin plays a prominent role in QCD, the theory of strong interactions between spin-1/2 quarks and spin-1 gluons. Historically, there have been many examples of how polarization measurements have forced us to change the way in which physical processes are viewed. It was obvious from this workshop that there remain many important open questions in nuclear and particle physics that require further polarization measurements in the hadronic sector. Although the majority of the experiments discussed in this session involved lepton-hadron and hadron-hadron reactions, it should be emphasized that the nucleus further provides a powerful laboratory in which to test our understanding of QCD in a strongly interacting medium
[en] It is argued that hadron collisions with nuclei are similar to hadron-hadron collisions, having similar properties for the impact parameter distributions and the leading particle spectra. The relevant existing high-energy data, including the universality of multiplicity distributions and the possibility of geometrical scaling in reactions with nuclei, are easily understood in the framework of geometrical models by extending to p-nucleus collisions what was learnt about impact parameter and leading particles in pp collisions. The questions of forward-backward correlations and photo- and electroproduction are briefly discussed. (Auth.)
[en] A new mechanism for hadroproduction is proposed via a sequence of period-doubling bifurcations of the relevant phase trajectories. The intermittency phenomenon as a manifestation of this mechanism is discussed. 21 refs., 8 figs
[en] We present an overview of recent improvements of hadronic models in Geant4 for the physics configurations (Physics Lists) relevant to applications in high energy experiments. During last year the improvements have concentrated on the study of unphysical discontinuities in calorimeter observables in the transition regions between the models used in Physics Lists. The microscopic origin of these have been investigated, and possible improvements of Geant4 code are currently under validation. In this paper we discuss the status of the latest version of Geant4 with emphasis on the most promising new developments, namely the Fritiof based and CHIPS Physics Lists.
