Superstring theory and its successor, M-theory, hold promises of a deeper understanding of the Standard Model of particle physics, the unification of the four fundamental forces, the quantum theory of gravity, the mysteries of quantum black holes, Big Bang cosmology and, ultimately, their complete synthesis in a final theory of physics.This volume records the proceedings of the major annual international conference on the subject, ?Strings 2000?, which involved 42 talks by the world's leading experts on string theory and M-theory. It will be of interest not only to researchers in the field but also to all those who wish to keep abreast of the latest developments and breakthroughs in this exciting area of theoretical physics.

String phenomenology offers a bridge between the excitement and novelty that typified theoretical physics in recent years and experimental reality. The First International Conference on String Phenomenology concentrated on cosmological and phenomenologically oriented applications of string theory. The aim was to bring together experimental and theoretical physicists to discuss the triumphs and challenges that high energy physics faces in its attempt to uncover the next layers of fundamental matter and interactions. The main theme was the application of string theory, but the conference also accommodated alternative approaches to physics beyond the Standard Model. The conference featured plenary talks reviewing the major topics, as well as parallel sessions for contributed papers describing new results in the major areas of the conference. It covered diverse topics, from collider and neutrino physics to fibre bundles on Calabi-Yau three folds.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)

Many of the topics in this book are outgrowths of the spectacular new understanding of duality in string theory which emerged around 1995. They include the AdS/CFT correspondence and its relation to holography, the matrix theory formulation of M theory, the structure of black holes in string theory, the structure of D-branes and M-branes, and detailed development of dualities with N = 1 and N = 2 supersymmetry. In addition, there are lectures covering experimental and phenomenological aspects of the Standard Model and its extensions, and discussions on cosmology including both theoretical aspects and the exciting new experimental evidence for a non-zero cosmological constant.
