This book includes four chapters about quarks, which are a type of elementary particle and a fundamental constituent of matter. Chapter One is devoted to spectroscopy study of long-range quark-lepton strong interaction in solids as well as the origin of the mass of elementary particles. Chapter Two studies the production of top-quark pairs with a Higgs boson. Chapter Three begins with a brief historical outline of the development of the events that led to our understanding of quarks and analyzes the three families of quarks. Chapter Four discusses strange quark matter and strange quark stars as candidates for dark matter based on the Bodmer-Terazawa-Witten hypothesis.

This book shows how the study of multi-hadron production phenomena in the years after the founding of CERN culminated in Hagedorn's pioneering idea of limiting temperature, leading on to the discovery of the quark-gluon plasma -- announced, in February 2000 at CERN.Following the foreword by Herwig Schopper -- the Director General (1981-1988) of CERN at the key historical juncture -- the first part is a tribute to Rolf Hagedorn (1919-2003) and includes contributions by contemporary friends and colleagues, and those who were most touched by Hagedorn: Tamás Biró, Igor Dremin, Torleif Ericson, Marek Gaździcki, Mark Gorenstein, Hans Gutbrod, Maurice Jacob, István Montvay, Berndt Müller, Grazyna Odyniec, Emanuele Quercigh, Krzysztof Redlich, Helmut Satz, Luigi Sertorio, Ludwik Turko, and Gabriele Veneziano.The second and third parts retrace 20 years of developments that after discovery of the Hagedorn temperature in 1964 led to its recognition as the melting point of hadrons into boiling quarks, and to the rise of the experimental relativistic heavy ion collision program. These parts contain previously unpublished material authored by Hagedorn and Rafelski: conference retrospectives, research notes, workshop reports, in some instances abbreviated to avoid duplication of material, and rounded off with the editor's explanatory notes.About the editor: Johann Rafelski is a theoretical physicist working at The University of Arizona in Tucson, USA. Born in 1950 in Krakow, Poland, he received his Ph.D. with Walter Greiner in Frankfurt, Germany in 1973. Rafelski arrived at CERN in 1977, where in a joint effort with Hagedorn he contributed greatly to the establishment of the relativistic heavy ion collision, and quark-gluon plasma research fields. Moving on, with stops in Frankfurt and Cape Town, to Arizona, he invented and developed the strangeness quark flavor as the signature of quark-gluon plasma.

In 1980, the Cold War was in full bloom. The Soviet father of the hydrogen bomb and Nobel Peace Laureate turned dissident physicist, Andrei Sakharov, had been exiled to Gorki by the Soviet authorities. Called “senile” and under heavy Soviet censorship, Sakharov had a hard time communicating his latest scientific results to readers outside of Gorki. Some smuggled results reached the author, Harry Lipkin, who then realized that he and Sakharov were both pioneers in a new revolution on our understanding the structure of matter. The particle physics community had resisted their revelation that the accepted building blocks of matter, neutrons and protons, were composed of tinier building blocks called “quarks”. What followed was a remarkable adventure in which both scientists fought the Soviet censors, smuggling postcards and manuscripts into and out of the Soviet Union while trying to further scientific progress.Against a backdrop of politics, suppression, and genius, Andrei Sakharov, Quarks and the Structure of Matter details the search for the basic building blocks of matter, the path to understanding the forces that bind them together, and how scientific knowledge is learned, communicated and passed from one group of investigators to another.

Mitten in Europa ist eine der größten und komplexesten Maschinen in Betrieb gegangen, die wir Menschen je gebaut haben: der Large Hadron Collider (kurz LHC). Mit ihm öffnet sich ein Fenster in eine neue Welt, die viele Geheimnisse birgt: Was verleiht den Teilchen der Materie ihre Masse? Gibt es verborgene Raumdimensionen? Existiert ein tiefer Zusammenhang zwischen Teilchen mit verschiedenem Spin (Supersymmetrie)? Woraus besteht die dunkle Materie, die unser Universum durchdringt? Mit diesem Buch taucht der Leser ein in diese wunderbare Welt, die wir Menschen in der Neuzeit entdeckt haben: Atome und ihre Substruktur aus Quarks und Leptonen, die rätselhafte Quantenmechanik, Teilchen des Lichts, Einsteins Gewebe aus Raum und Zeit, die vier Wechselwirkungen und schließlich die neue Welt, in die der LHC gerade vordringt und in der wir Higgs-Teilchen, Supersymmetrie und womöglich erste Anzeichen für die String-Theorie vermuten. Nach der Lektüre ist klar: Wir leben in einer erstaunlichen Welt und sind gerade im Begriff, bei der Enträtselung ihrer Geheimnisse einen entscheidenden Schritt nach vorne zu gehen.

Not since Newton's apple has there been a physics phenomenon as deliciously appealing to the masses as Frank Close's Cosmic Onion. Widely embraced by scientists and laypersons alike, the book quickly became an international bestseller. Translated into seven languages, it propelled the author to become a worldwide celebrity as well as an inspi

This is an updated version of the book published in 1985. QCD-motivated, it gives a detailed description of hadron structure and soft interactions in the additive quark model, where hadrons are regarded as composite systems of dressed quarks.In the past decade it has become clear that nonperturbative QCD, responsible for soft hadronic processes, may differ rather drastically from perturbative QCD. The understanding of nonperturbative QCD requires a detailed investigation of the experiments and the theoretical approaches. Bearing this in mind, the book has been rewritten paying special attention to the interplay of soft hadronic collisions and the quark model. It is at the crossroads of these domains that peculiar features of strong QCD reveal themselves.The book discusses constituent quarks, diquarks, the massive effective gluons and the problem of scalar isoscalar mesons. The quark-gluonium classification of meson states is also given. Experimentally observed properties of hadrons are presented together with the corresponding theoretical interpretation in the framework of the composite hadron structure.The text includes a large theoretical part, which shows how to treat composite systems (including relativistic ones) with a technique based on spectral integration. This technique provides the possibility of handling hadrons as weakly bound systems of quarks and, at the same time, takes into account confinement.Attention is focused on the composite structure revealing itself in high energy hadron collisions. Fields of applicability of the additive quark model are discussed, as is colour screening in hadronic collisions at high and superhigh energies. Along with a detailed presentation of hadron-hadron collisions, a description of hadron-nucleus collisions is given.

This book describes baryon models constructed from quarks, mesons and chiral symmetry. The role of chiral symmetry and of quark model structure with SU(6) spin-flavor symmetry are discussed in detail, starting from a pedagogic introduction. Emphasis is placed on symmetry aspects of the theories. As an application, the chiral bag model is studied for nucleon structure, where important methods of theoretical physics, mostly related to the semiclassical approach for a system of strong interactions, are demonstrated. The text is more practical than formal; tools and ideas are explained in detail while solving actual problems. By checking each step of the computations, readers can learn not only the calculational techniques but also the essential ideas behind them.

This book comprises an introduction to the theory of the weak interaction of elementary particles.The author outlines the current situation in weak interaction theory and discusses the prospects for the coming decade. The reader is familiarized with simple theoretical techniques for the calculation of decay rates, interaction cross-sections and angular and spin correlations.

The discovery of the two families of heavy-quark-antiquark bound states, the &Ugr; and &PSgr; quarkonium spectroscopies, has played a crucial role in unravelling the nature of strong interactions. The articles collected together in this volume are concerned with the connection between quarkonia and quantum chromodynamics. They deal with potential models, spin-dependent forces, next-to-leading order QCD corrections for decay widths and energy level differences, hadronic transitions and the quark-antiquark interaction in QCD, based on perturbation theory, lattice gauge theory and QCD sum rules. Finally, a brief guide is given to the existing literature on possible new quarkonium systems which have been conjectured in connection with gluonic degrees of freedom, and with expectations for new heavy particles with colour, such as the top quark and scalar quarks.
