Book Description
This volume contains the greater part of the papers submitted to the High Energy Physics portion of the 1983 Orbis Scientiae, then dedicated to the eightieth year of Professor P. A. M. Dirac. Before the vol,ume could be published, Professor Dirac passed away on October 20, 1984, thereby changing the dedication of this volume, and its companion, on Information Processing in Biology, to his everlasting memory. Since 1969, Professor Dirac had given the opening address at each of these conferences. He was unable to prepare a manuscript of his last paper in 1983. His impact on science already has been enormous. The consequences of his thought and work for future developments are incalculable. Regrettably, Professor Dirac's last appearance at this series of conferences, begun in 1964 as the Coral Gables Conference on Symmetry Principles at High Energy, coincided with the twentieth, and the last of these. The work and expense involved in organizing them and preparing the proceedings have corne to far exceed the physical capabilities and the support received by the Center for Theoretical Studies for this program. The delayed appearance of these proceedings, for which the editors humbly apologize, is a manifestation of the inadequate support. On the other hand, the organizers and editors thank the many distinguished participants who, over the years, made these meetings exciting and productive arenas for the dissemination of ideas in high energy physics and related fields.

Book Description
For the Galvani Bicentenary Celebrations, the University of Bologna and its Academy of Sciences singled out subnuclear physics as the field of scientific research to be associated with this important event, as it would best illustrate, for the new generation of students, the challenge inherent in fundamental sciences. Subnuclear physics was born 50 years ago and has represented, ever since, the new frontiers of Galilean science. In his opening lecture delivered on the first day of the new academic year, Professor Antonino Zichichi analytically reviewed the basic conceptual developments and main discoveries achieved in subnuclear physics during the last 50 years. Given the importance of this field of fundamental research, Professor Zichichi was invited to expand the contents of his lecture into a book, and the outcome is this invaluable volume.

Book Description
The observation of the scaling properties of the structure functions w and vw of deep inelastic electron 1 2 nucleon scattering [1]+ has been taken by many people as an indication for an approximate scale invariance of the world. It was pointed out by Wilson [2], that in many field theories it is possible to assign a dimension d to every fundamental field, which proves to be a conserved quantum number as far as the most singular term of an operator product expansion at small distances ((x-y) +a) is con- JJ cerned++. Later it was shown, at the canonical level, that in many field theories the dimension of a field seems to be a c:pod quantum number even in the terms less singular at small (x-y) , as long as they all belong to the strongest \l light cone singularity (i. e. (x-y)2+a) [3]. The assumption that this type of scale invariance on the light cone be present in the operator product ex pansion of two electromagnetic currents has provided us with a rather natural explanation of the observed scaling phenomena. We should like to mention, however, that this ex planation cannot account for the precocity with which scaling is being observed experimentally in energy regions, in which resonances still provide prominent contributions to the final states [4].

Book Description
The fourth Advanced Study Institute (ASI) on Techniques and Concepts of High Energy Physics was held once again at the Hotel on the Cay, in the scenic harbor of Christiansted, St. Croix, U.S. Virgin Islands. The ASI brought together a total of 67 participants, from 17 different countries. It was a great success, due to the dedication of the inspiring lecturers, the exceptional student body, and, of course, the beautiful setting. The primary support for the meeting was again provided by the Scientific Affairs Division of NATO. The ASI was cosponsored by the U.S. Department of Energy, by Fermilab, by the National Science Foundation, and by the University of Rochester. A special contri bution from the Oliver S. and Jennie R. Donaldson Charitable Trust provided an important degree of flexibility, as well as· support for worthy students from developing nations. As in the case of the previous ASI's, the'scientific program was designed for advanced graduate students and recent PhD recipients in experimental particle physics. The present volume of lectures should complement the material published in the first three ASI's, and prove to be of value to a wider audience of physicists. It is a pleasure to acknowledge the encouragement and support that I have continued to receive from colleagues and friends in organizing this meeting. I am indebted to the members of my Advisory Committee for their infinite patience and excellent advice. I am grateful to my distinguished lecturers for participating in the ASI.

Book Description
The 1983 Cargese Summer Institute on Particles and Fields was organized by the Universite Pierre et Marie Curie, Paris (M. LEVY and J.-L. BASDEVANT), C.E.R.N. (M. JACOB), the Universite Catholique de Louvain (D. SPEISER and J. WEYERS), and the Katholieke Universiteit Leuven (R. GASTMANS). After 1975, 1977, 1979, and 1981, it was the fifth time they joined their efforts for organizing this Summer Insti tute. This school was characterized by simultaneous progress in the theory of elementary particles and by impressive experimental advances. On the theoretical front, one witnessed the new developments in lattice gauge theories, which explore the world of strongly interacting par ticles in a non-perturbative way, and progress in a better understan ding of the unity of all interactions based on supersymmetry. The experimentalists were ~roud to announce the discovery of the interme diate vector bosons; W- and ZO, at C.E.R.N., while physicists working with e+e- colliding beams continued to probe more deeply the validity of the theoretical models of strong, weak and electromagnetic inter actions. We owe many thanks to all those who have made this Summer Insti tute possible! Thanks are due to the Scientific Committee of NATO and its Presi dent for a generous grant and especially to the head of the Advanced Study Institute Program and his collaborators for their constant help and encouragement. We also thank the National Science Foundation (USA) for their financial assistance.

Book Description
In 1947 J. Robert Oppenheimer organized a historic conference of physicists at Shelter Island, located off the eastern tip of Long Island, to discuss recent advances in theoretical physics and the direction of future research. Over three decades later, the physics community held another meeting, the 1983 Shelter Island Conference on Quantum Field Theory and the Fundamental Problems of Physics. This volume is the record of the 1983 conference; it also includes much valuable information on the 1947 conference, for which no formal proceedings were ever published. The latter-day conference included many of the participants from the prior event as well as younger physicists who have since become prominent figures in this field. Consequently, this volume is a vital document in the history of physics, of value to students and researchers in many branches of the subject. Topics include the new inflationary universe scenario; supersymmetry; Stephen Hawking's presentation, "The Cosmological Constant Is Probably Zero"; superunification and the seven-sphere; time as a dynamical variab≤ induced gravity; and an extensive and previously unpublished paper by Edward Witten on Kaluza-Klein theories. Contributors include Stephen L. Adler, Hans Bethe, M. J. Duff, Murray Gell-Mann, Alan H. Guth, Stephen W. Hawking, Roman Jackiw, Toichiro Kinoshita, W. E. Lamb, Jr., T. D. Lee, A. D. Linde, R. E. Marshak, Y. Nambu, K. Nishijima, John H. Schwarz, Silvan S. Schweber, Steven Weinberg, Victor Weisskopf, P. C. West, Edward Witten, and Bruno Zumino.
