Seifallah Randjbar-daemi - Böcker

This School presented topics of current interest in high energy physics including Superstrings, Unified Theories and Cosmology.

Over the last two decades, topological ideas have found increasingly more applications in quantum field theory. Topological field theories are the culmination of these developments, and they formed the dominating theme of the conference. The other focal point was two-dimensional quantum gravity. The participation of such leading mathematicians as M Atiyah, R Bott, G Segal, and I Singer, is a testmony to the deep interplay of mathematics and theoretical physics.

The aim of this interdisciplinary conference was to bring together experts in quantum field theory and condensed matter physics to survey the latest exciting developments in this border-line field, such as the Chern-Simons field theory and quantum hall effect, anyon superconductivity, Yang-Baxter equations and quantum groups, conformal field theory and multi-channel kondo effect, matrix models and quantum gravity, etc.This set of proceedings contains brief reviews contributed by leading experts in the field.

This volume is a collection of papers presented at the Summer School, ICTP, 14 June - 30 July. Topics covered include: comparing the elementary quark versus the preonic approach to unification, quark matter and nuclear collisions and effective actions and topological string amplitudes.

The proceedings of the Annual Trieste Summer School on High Energy Physics and Cosmology covers many of the leading research areas in these fields. They are valuable resources for active researchers, including advanced graduate students as well as postdoctoral fellows.

In this volume recent developments in the nonperturbative aspects of string theory, duality in N = 1 string compactifications, orientifolds and F-theory as well as the matrix model description of M-theory are reported. The D-brane approach to black holes and their entropy is also discussed.The phenomenological part is devoted to the main fields of present-day astroparticle physics: supersymmetry, neutrino physics and cosmology. The two most important aspects of supersymmetry are covered: Searches for superpartners (G Kane) and mechanisms of supersymmetry breaking (G Dvali).Results from recent neutrino experiments and their implications are presented (S Pakvasa). The central issues of modern cosmology such as inflation (R Brandenberger), formation of topological defects (T Vachaspati) and dark matter (M Kamionkowski) are discussed.

A volume of proceedings from the 1999 Spring Workshop on Superstrings and Related Matters, held in Trieste, Italy. Subjects covered include: large N gauge theories and ADS/CFT correspondence; black holes physics; duality and instantons in string theory; D-branes and F-theory; and more.

In this volume, topics such as the AdS/CFT correspondence, non-BPS states, noncommutative gauge theories and the Randall-Sundrum scenario are discussed. For the AdS/CFT correspondence, some of its generalizations, including examples of non-AdS/nonconformal backgrounds, are described. Myer's effect in this context and otherwise is also treated. Recent results in the context of non-BPS states are reviewed, in particular the use of open string field theory in understanding the related problem of tachyon condensation. Instantons and solitons in noncommutative gauge theories are described, as are various issues in the framework of the Randall-Sundrum scenario.

The ICTP has been holding a Summer Workshop in High Energy Physics and Cosmology since 1981. The primary goal of these workshops is to bring together active physicists from around the world, and to provide a platform where the frontier developments in the field are presented by leading workers. The atmosphere for the workshop was active and stimulating and each area was represented by leading physicists in the field.
