Cosmo 97

Deciphering the script for the Big Bang has now become a joint effort of particle physicists and cosmologists. The origin and first moments of the early Universe were determined by the same fundamental processes which are studied in terrestrial accelerators and whose traces from the early Universe can be seen in astrophysical observations. It is now almost universally accepted that most of the debris left over from the Big Bang is likely to be in the form of particle dark matter. Identifying its nature and measuring its abundance in the Universe have become major goals of theorists and experimentalists alike. This volume reviews the progress made at the frontiers of research in these rapidly expanding fields. A broad range of topics, from inflation to primordial black holes to physics at the Planck era, and to dark matter and neutrinos — both reviews and reports on the most recent advances — is presented by leaders in the field.

The PASCOS (International Symposium on Particles, Strings and Cosmology) series brings together the leading experts and most active young researchers in the closely related fields of elementary particle physics, string theory and cosmology/astrophysics. These areas of research have become increasingly intertwined in recent years, each having direct impact on the others. In particular, there has been a dramatic expansion of ideas from particle theory and string theory that have vast impact on cosmology, especially our picture of the early universe and its evolution. Correspondingly, the proliferation of data regarding the early universe, and its increasing precision, has begun to strongly constrain the theoretical models. Meanwhile, observations of neutrino oscillations and cosmic ray excesses, and limits on new physics from colliders and other particle experiments, as well as the resulting restrictions on theoretical and phenomenological modeling, are becoming ever stronger. During PASCOS99, it became clear that the long-awaited era of convergence of these fields is truly at hand.The proceedings of PASCOS 99 reflect the accelerating overlap and convergence of the fields of elementary particles physics, string theory and cosmology/astrophysics. Plenary reviews by leading figures in these fields provide perspectives on these interrelationships and up-to-the-minute summaries of recent progress in the various areas. Parallel talk summaries focus on many of the topics within each field of greatest current interest and activity. Both the plenary and parallel writeups are designed to be descriptive in nature and avoid being overly technical. As a result, the volume can serve as a useful reference for students and professionals in all three fields. Careful referencing allows further pursuit of a given topic. Overall, the proceedings are unique in that they not only bring together in a single volume comprehensive overview of the great progress being made in all three of these very exciting fields, but also provide a snapshot of how particles, strings and cosmology are increasingly impacting one another.

Neutrinos are one of the most abundant particles in the universe. Because they have very little interaction with matter, however, they are incredibly difficult to detect. Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons. Three types of neutrinos are known. Each type or 'flavour' of neutrino is related to a charged particle (which gives the corresponding neutrino its name). Hence, the 'electron neutrino' is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the muon and the tau.
