th This workshop was the 15 in a series that addresses the subject of the dynamics of nuclear reactions. These workshops are dedicated to the concept that bringing together scientists from diverse areas of nuclear reactions promotes the vibrant exchange of ideas. This workshop hosted presentations from experimentalists and theorists, intermediate energy to ultrarelativistic energies, and final results to recent speculations. Many of these scientists would not normally be exposed to the work done in other subfields. Thus the Winter Workshop on Nuclear Dynamics plays a unique role in information exchange and the stimulation of new ides. The field of nuclear dynamics has a bright future. New accelerators are being planned and completed around the world. New detectors are being constructed. New models and theories are being developed to describe these phenomena. The Winter Workshop on Nuclear Dynamics will continue to promote this lively and compelling field of research. WOLFGANG BAUER AND GARY D. WESTFALL v Previous Workshops The following table contains a list of the dates and locations of the previous Winter Workshops on Nuclear Dynamics as well as the members of the organizing committees. The chairpersons of the conferences are underlined.

The Conference OC Bologna 2000: Structure of the Nucleus at the Dawn of the CenturyOCO was devoted to a discipline which has seen a strong revival of research activities in the last decade. New experimental results and theoretical developments in nuclear physics will certainly make important contributions to our knowledge and understanding of Nature's fundamental building blocks. The interest aroused by the Conference among the scientific community was clearly reflected in the large number of participants. These represented the most important nuclear physics laboratories in the world. The Conference covered five major topics of modern nuclear physics: nuclear structure, nucleusOConucleus collisions, hadron dynamics, nuclear astrophysics, and transdisciplinary and peaceful applications of nuclear science. It reviewed recent progress in the field and provided a forum for the discussion of current and future research projects. Contents: Quark and GluonOCoPlasma Phase Transition and Relativistic Heavy-Ion Reactions; LiquidOCoGas Phase Transitions in Nuclear Matter; Nuclear Caloric Curve and Thermodynamics of Heavy Ion Collisions; Statistical and Dynamics Aspects of Fragmentation; Intermediate Energy Heavy-Ion Reactions; Reaction Mechanisms around the Barrier. Fusion and Fission in Heavy-Ion Reactions. Readership: Nuclear physicists."

The first precision measurements on CP violation in the B system are reported. Both the BELLE and the BABAR collaboration presented, among others, results for sin 2ß with much improved accuracy. Results from the Sudbury Neutrino Observatory, SNO, also deserve to be mentioned. The convincing evidence of solar neutrino oscillations had been presented by SNO prior to the conference; a full presentation was given at the conference. An incredibly precise measurement of the anomalous magnetic moment of the muon is reported, a fresh result from the Brookhaven National Laboratory. Apart from these distinct physics highlights, there are also the first results from the new Tevatron run and from the relativistic heavy ion collider RHIC. Theorists write of our ever better understanding of the Standard Model and of what might lie beyond. Risky as it is to highlight only a couple of exciting subjects, it is merely meantto whet the appetite for further reading.

This book focuses on the state of the art of Monte Carlo methods in radiation physics and particle transport simulation and applications. Special attention is paid to algorithm development for modeling, and the analysis of experiments and measurements in a variety of fields.

These proceedings consist of plenary rapporteur talks covering topics of major interest to the high energy physics community and parallel sessions papers which describe recent research results and future plans.

This volume contains more than 80 papers by theorists and experimentalists in the field of multiparticle production. A large variety of domains in high energy physics are covered. For each of these domains, an overview is given before the newest results are presented.
