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 CalabiOCoYau three folds. The proceedings have been selected for coverage in: .

This book contains a remarkable overview of the current trends in string phenomenology, through the contributions of an international team of researchers who present their latest results. Dedicated to the memory of the late Professor Ian Kogan, this volume will fill a gap in the literature on a comprehensive overview of the subject.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences

Recent experimental results with direct bearing on theories of cosmological dark matter/energy, as well as continuing work on neutrino masses and mixing, have invigorated both particle physics and cosmology, and should continue to do so well into the 21st century, thereby launching a beautiful new epoch for these fields. The expert contributions from this conference took stock of these developments. This volume contains papers by over 40 physicists that summarize and interpret the newest findings, and suggest future avenues to be explored. A number of new theoretical ideas are also presented, dealing with progress in understanding the dynamics and symmetries of strings and branes, renormalization in quantum field theory, possible Lorentz violation effects, and related problems. Ongoing and next generation gravitational and neutrino experiments are described, and the issues of unification are dealt with in the context of, and beyond, the standard model. Together, the contributions provide a useful blend of experimental and theoretical physics from many prominent physicists, including three Nobel Laureates. The volume also contains information of an historical nature, concerning the contributions to physics by Paul Frampton, on the occasion of his 60th year, and summarizing the career of Behram Kursunoglu (1922-2003).

This book addresses the theoretical, phenomenological and experimental aspects of supersymmetry in particle physics as well as its implications in cosmology.

During its forty year lifespan, string theory has always had the power to divide, being called both a 'theory of everything' and a 'theory of nothing'. Critics have even questioned whether it qualifies as a scientific theory at all. This book adopts an objective stance, standing back from the question of the truth or falsity of string theory and instead focusing on how it came to be and how it came to occupy its present position in physics. An unexpectedly rich history is revealed, with deep connections to our most well-established physical theories. Fully self-contained and written in a lively fashion, the book will appeal to a wide variety of readers from novice to specialist.

This volume presents the progress made in the study of the Seesaw mechanism and of its implications over the past 25 years, as well as the recent theoretical developments in the understanding of the measured pattern of neutrino masses and mixings. Observable implications of the Seesaw mechanism like leptogenesis or lepton flavour violation in supersymmetric theories are discussed, and the key aspects of the vast experimental program aimed at determining the neutrino parameters and properties are reviewed. The book provides an up-to-date and in-depth perspective on neutrino masses and on the associated physics in the Seesaw scenario.
