The ASI Quarks, Leptons and Beyond, held in Munich from the 5th to the 16th of September 1983 was dedicated to the study of what we now believe are the fundamental building blocks of nature: quarks and leptons. The subject was approached on two levels. On the one hand, a thorough discussion was given of the status of our knowledge of quarks and leptons and their interactions, both from an experi mental and a theoretical standpoint. On the other hand, open problems presented by the so called standard model of quark and lepton interact ions were explored along various ways that lead one beyond this frame work. One of the principal predictions of the standard model is that weak interactions are mediated by heavy Wand Z vector bosons. These particles were discovered in 1983 at CERN and their relevant proper ties were discussed at the ASI by C. Rubbia. Further theoretical predictions concerning these Z and W bosons, yet to be checked by future experimentation, were discussed by G. Altarelli with a view of seeing where the standard model might fail and new physics ensue. The strong interactions of quarks, based on Quantum Chromodynamics (QeD), are presumed to cause the quarks to bind into hadrons. Pro gress in attempts to calculate the observed hadronic spectrum, ab initio, starting from QCD and employing lattice methods were reviewed at the ASI by P. Hasenfratz.

Beyond the Nanoworld

This books deals with the structures we find when we look beyond the nanoworld, namely leptons, quarks and gauge bosons.

Beyond the world of atoms, at scales smaller than the smallest nuclei, a new world comes into view, populated by an array of colorful elementary particles: strange and charmed quarks, muons and neutrinos, gluons and photons, and many others, all interacting in beautifully intricate patterns. Beyond the Nanoworld tells the story of how this new realm was discovered. From the first discoveries of subatomic structure to the present-day hunt for the Higgs particle, the reader is invited to follow the twin branches of experimental and theoretical research as they wind through the twentieth century, culminating in the most successful physical theory of all time: the standard model of particle physics.

Masses And Mixings Of Quarks And Leptons

Striking feature of mass spectra and mixings[1] of the quarks and leptons is the hierarchical structure, which is hints for the beyond SM. In the quark-lepton mass matrices, there are 54 parameters: Mu : 3 × 3 × 2 ...

It is widely accepted that quarks and leptons should be understood on the basis of the same unification scheme. The investigation of hidden rules behind observed quark and lepton mass spectra will provide a very important clue to a unified model of quarks and leptons. Now the investigation is timely because of the recent abundance of data on the CKM matrix elements and neutrino mixings. This volume offers useful information and hints on a unified understanding of quarks and leptons.

The present volume is based on the proceedings of the 6th and 7th INFN ELOISATRON project workshops, held at the Centro di Cultura Scientifica "Et tore Majorana" CCSEM, Erice-Trapani, Sicily, Italy, in the period June 10-27, 1988. The topics of the two workshops were, respectively: - Heavy Flavours: Status and Perspectives, and - Novel Features of High Energy Collisions in 1-100 TeV Region. They were attended by sixty-three physicists. The two workshops were followed by a meeting of the INFN ELOISATRON working group, also held at the CCSEM in the period October 7-15, 1988 in which twenty-five physicists participated. Since there was quite a bit of overlap among speakers, participants and the topics covered at the three meetings, we have decided to issue ajoint proceeding, with the first part entitled: Heavy Flavour Physics, and the second: High Energy Physics with 1-100 Te V Proton Beams. Some of the reports included in this volume have been contributed by the INFN ELOISATRON working group members. The first. part of these proceedings deals mostly with the presentation and inter pretation of results in t.he so-called fiavour physics sector. New results, which have become available in the last three years from experiments involving kaons, charmed and beauty hadrons, and searches for the still missing top quark at the present and fothcoming colliders are topics of major interest. here. The contributions in this part are organized in three categories: Experimental Results, Theoretical Interpretation, and Future Directions.

Surveys the latest developments in the field of physics, in such areas as quantum theory, low-temperature physics, astrophysics, relativity, and quarks

Status and Plans of the United States and CERN High Energy Physics Programs and the Superconducting Super Collider SSC

Other questions beyond its reach abound : Are quarks and leptons really basic , or are they composites of more basic entities ? Are there unifications of forces beyond the electroweak unification of the Standard Model ?
