Particle Phenomenology In The 90's - Proceedings Of The Workshop In High Energy Physics Phenomenology Ii


Book Description

Second in a series of international workshops in high energy physics, WHEPP II dealt with front- line areas of particle phenomenology with an eye to new physics with planned accelerators. Among the topics discussed were: (a) collider physics and structure functions, (b) B physics, hadronic matrix elements and lattice results, (c) new particle search and model building, (d) LEP results and radiative corrections to electro-weak processes and (e) baryon number violation in electroweak processes.

Electroweak Effects at High Energies


Book Description

The first Europhysics Study Conference on Electroweak Effects at High Energies was held at the "Ettore Majorana" Centre for Scientific Culture in Erice, Sicily from February 1 -12, 1983. The conference was attended by 61 physicists from 11 countries. The conference was sponsored by the European Physical Society, the Italian Ministry of Public Education, the Italian Ministry of Technological Research, the Sicilian Regional Government and the California Institute of Technology. CONFERENCE FORMAT The Study Conference followed a new intensive format in which the state of our knowledge of the electroweak interaction, and the relation of the electroweak sector to Grand Unified and Superunified Theories was reviewed in some depth. During the two week conference, 54 experimental and theoretical talks were presented, and four evening discussion sessions were held. The Erice surroundings, the wide-ranging conference program, and the fact that nearly all of the participants were directly involved in recent major experimental or theoretical developments, led to animated and very friendly discussions. Participants had the rare opportunity to view most of the major trends in high energy physics in a short interval of time, and to discuss and contemplate the trends in the uniquely peaceful yet stimulating atmosphere which is an Erice tradition.




The Standard Electro-Weak Theory – 2nd Edition


Book Description

This book is the natural follow-on of the discussion about Quantum Electro Dynamics (QED), begun with my former manual ''Alkali Atomic spectra'', mainly concerning with the description of the atom structure. The Theory of Fields, and then the whole Standard Model, concern particles in relativistic motion. There an atom is ionized and nuclei and particles are brought to collide at relativistic energies. In order to investigate the dynamics an appropriate model is needed. Particles are represented as fields and those fields are themselves quantized as for second quantization. The definition of the Electro-Weak theory and the concept of symmetry breaking are just the prelude to all the physics behind Supersymmetry and Gravitation, and eventually to the Grand Unification Theories (GUT).




Applied N


Book Description

These lectures give an elementary introduction to the important recent developments of the applications of N=1 supergravity to the construction of unified models of elementary particle interactions. Topics covered include couplings of supergravity with matter, spontaneous symmetry breaking and the super-higgs effect, construction of supergravity unified models, and the phenomenon of SU(2) x U(1) electroweak-symmetry breaking by supergravity. Experimental consequences of N-1 supergravity unified theory, in particular, the possible supersymmetric decays of the W± and Z0 bosons, are also discussed. The treatment presented encompasses a broad class of models, both of the tree breaking as well as the radiative breaking of SU(2) x U(1). Rules of tensor calculus and the explicit construction of the Lagrangian of the Supergravity-matter couplings are given in the appendix.







Techniques and Concepts of High-Energy Physics II


Book Description

The second Advanced Study Institute (ASI) on Techniques and Concepts of High Energy Physics was held at the Roaring Brook Resort at Lake George, New York. As in the case of the first ASI, our aim was to bring together a small group of promising young ex perimenters and several outstanding senior scholars in high energy physics in order to learn about the latest trends in the field and develop stronger contacts among scientists from different countries and different backgrounds. The setting at Roaring Brook was particularly congenial and the staff, under the direction of George Green, was both friendly and efficient. The ASI was supported mainly through funds provided by the Scientific Affairs Division of NATO. It was cosponsored by the U. S. Department of Energy, Fermilab, the National Science Founda tion and the University of Rochester. A special grant from the Oliver S. and Jennie R. Donaldson Charitable Trust provided a valuable degree of flexibility for supporting worthy students. The scientific program of this ASI was, once again, designed primarily for advanced graduate students and recent Ph.D recipients in experimental particle physics. I believe, however, that the contents of the present volume will prove useful to an even wider audience of physicists.




Electroweak Symmetry Breaking And New Physics At The Tev Scale


Book Description

This is an expanded version of the report by the Electroweak Symmetry Breaking and Beyond the Standard Model Working Group which was contributed to Particle Physics — Perspectives and Opportunities, a report of the Division of Particles and Fields Committee for Long Term Planning. One of the Working Group's primary goals was to study the phenomenology of electroweak symmetry breaking and attempt to quantify the “physics reach” of present and future colliders. Their investigations encompassed the Standard Model — with one doublet of Higgs scalars — and approaches to physics beyond the Standard Model. These include models of low-energy supersymmetry, dynamical electroweak symmetry breaking, and a variety of extensions of the Standard Model with new particles and interactions. The Working Group also considered signals of new physics in precision measurements arising from virtual processes and examined experimental issues associated with the study of electroweak symmetry breaking and the search for new physics at present and future hadron and lepton colliders.This volume represents an important contribution to the efforts being made to advance the frontiers of particle physics.
