[en] This volume contains papers from leading authorities, who examine recent topics in both theoretical and experimental subnuclear physics. These include the theory of new particles, the problem of quark status and of their confinement in terms of the bag model, the phenomenology of e⁺e^- reactions, neutral and charged weak currents, and deep inelastic phenomena. The highlight of the book is a special session entirely devoted to the most popular theory of the subnuclear colored strong forces: quantum chromodynamics

[en] This volume brings together physicists from around the world to report and discuss the exciting advances made recently in theoretical and experimental aspects of gauge interactions. Following a presentation of the theoretical foundations of and recent developments in gauge fields, the contrib utors fogus on supersymmetry, the derivation of Higgs particles from gauge fields, and heavy leptons. Other chapters discuss the use of quantum chromodynamics in describing basic interactions among quarks and gluons, in predicting the existence of glueballs, and in application to heavy flavor production in strong interactions. The editor, Antonino Zichichi, provides a study of the multiparticle hadronic systems produced in highenergy soft (pp) interactions. Other interesting chapters deal with photon scattering at very high energies and theoretical alternatives to the electroweak model, and the volume concludes with proposals for future experimental facilities for European physics

[en] The contents of this volume take the form of theoretical lectures, seminars on specialized topics, and review lectures. Individual subjects explored include the nonlocal U(2) gauge theory, SU(5) without SU(5), the electroweak program for the 1980s, the theoretical implications of Isabelle physics, the Bianchi-Backlund transformations, the Grand Unification, Planck energy and subnuclear physics, the link between pp and e⁺e^- phenomena, the nonexistence of ''molecular quark states,'' ''oo'' resonance, the status of e⁺e^- physics in the United States, the e⁺e^- PETRA machine, ''deep inelastic'' phenomena induced by charged leptons and those induced by neutrinos, the Orsay e⁺e^- experiment in the ''low''-energy range, the possible existence of more than one Z⁰, the possible existence of baryon instability, the status of ''charmed'' particles, the ''theoretical desert,'' and the heavy lepton and the consequences of its discovery for the frontiers of subnuclar physics

[en] Directed toward the discovery of a more accurate unified theory of all the forces of nature, the new aspects of subnuclear physics focuses on two important areas of contemporary research: supersymmetry and electroweak interactions. The first half of the book examines supersymmetric theories of fundamental interactions and their consequences in nature, including the existence of such new particles drastically different from all known ones as the photino and the gluino. Other important chapters cover low-energy hadron physics with chromodynamics, neutrino physics, and e⁺e^- interactions. The second part of the volume includes a set of review lectures on topics of great current interest, such as What can be learned from superliquid ³He. and Is confinement the ultimate truth. In addition, the production and decay of charmed particles in e⁺e^- collisions are investigated, recent results from Gargamelle are scrutinized, and past successes and failures in mathematical physics are reviewed

[en] This book presents information on the following topics: elementary particle physics today; discrete mechanics; lattice calculations in gauge theory; the U(1) problem: instantons, axions, and familons; spontaneous supersymmetry breaking in N=1 and N=2 supergravity theories coupled to matter systems; testing supersymmetry; composite W-bosons and their dynamics; inclusive decay of heavy flavors; spin dependence and tests of QCD; physics results of the UAI collaboration at the CERN proton-antiproton collider; analysis of the hadronic final states at the CERN pp collidor; the problem of new heavy flavors (Top and superbeauty); QCD at the collidor; tests of QCD at PETRA; status of the glueballs; universitality features in (pp), (e⁺e^-), and deep inelastic scattering process; and events, laws of nature, and invariance principles

[en] This book offers a collection of authoritative papers which provides the reader with a plenary survey of some of the latest developments in the field of high-energy interactions. The contributing physicists offer a comprehensive review of recent significant findings from both theoretical and experimental studies in high-energy interactions. Topics include the end of the high-energy frontier, monopoles, numerical studies of gauge field theories, expectations for the next generation of experiments, unified models, cosmology, supersymmetry, neutrino physics at Fermilab, heavy flavor production in the highest-energy (pp) interactions, b-quark physics, hadron production in e⁺e^- annihilation, the search for new particles and electroweak interference effects in e⁺e^- interactions, CP violation, and high-energy soft (pp) interactions. Includes essays by Edward Teller and P.A.M. Dirac on their lives as physicists, and one by E.P. Wigner on ''the glorious days of physics.''

[en] This paper discusses the use of the correct variables in (pp), (e⁺e^-), and deep-inelastic scattering (DIS) processes which allow universality features to be established different ways of producing mulihadronic states. The experimental data where (pp) interactions are compared with (e⁺e^-) are shown. Extrapolations of collider physics are discussed and it is found that the leading effects must be subtracted and the correct variables have to be used if one wants to compare purely hadronic interactions with (e⁺e^-) and DIS. The new method of studying (pp) and (pp) collisions allows one to put on equal footing the multiparticle systems that are produced in purely hadronic interactions, in (e⁺e^-) annihilation, and in DIS processes

[en] The author considers the ratio between the masses of the known heavy quarks as a limit for the regularity in their masses. A diagram shows how a gluino can acquire a mass from radiative processes where a spin 1/2 quark and a spin O antiquark are virtually produced. The quark mass must be in the 10² GeV/c² range, in order to allow a gluino mass of the order of a few ''superbeauty'' in (pp) Collider energies. A brief review is ''superbeauty'' in (pp) Collider energies. A brief review is given of heavy flavors production in hadronic machines

[en] An overview of what has been learned in the areas of supersymmetry and the unified theory of weak and electromagnetic interaction, is outlined including a list of the five quantities needed to describe weak and electromagnetic processes in the framework of a theory that is renormalized. The three features of the Glashow-Salam-Weinberg theory are reviewed
