Book excerpt: Doctoral Thesis / Dissertation from the year 2007 in the subject Physics - Nuclear Physics, grade: 1,0, University of Frankfurt (Main) (Institut für Kernphysik), language: English, abstract: Quarks sind die elementaren Bestandteile, aus denen Hadronen (Baryonen und Mesonen) aufgebaut sind. Zusammen mit den Leptonen und den Eichbosonen gelten sie heute als die fundamentalen Bausteine, aus denen alle Materie aufgebaut ist. Im Standardmodell der Teilchenphysik werden diese Ergebnisse zusammengefasst. Es gibt sechs verschiedene Quark-Arten (flavours): up, down, strange, charm, bottom und top. In der Natur kommen keine isolierten Quarks vor, sondern nur Kombinationen aus z.B. einem Quark-Antiquark Paar (Meson) oder aus drei Quarks (Baryon). Die Quantenchromodynamik (QCD) beschreibt die starke Wechselwirkung zwischen Quarks und Gluonen. Quarks bauen unter anderem Protonen und Neutronen auf. Gluonen vermitteln die Wechselwirkung zwischen den Quarks. Konzeptionell ist die QCD an die Quantenelektrodynamik (QED) angelehnt, die die Wechselwirkung elektrisch geladener Teilchen (z.B. Elektron oder Positron) durch den Austausch von Photonen beschreibt. Analog wirkt die Kraft, die durch den Austausch von Gluonen beschrieben wird, zwischen Teilchen, die eine Farbladung (rot, grün, blau) tragen. Im Vergleich zur QED, wo das Photon neutral ist, trägt das Gluon selbst Farbe und wechselwirkt daher mit anderen Gluonen. Bei kleinen Quarkabständen und hohen Energien bzw. hohen Impulsüberträgen, fällt die Kopplungskonstante der starken Wechselwirkung (αs) ab. Bei kleinem αs sind Quarks und Gluonen schwach gebunden (Asymptotische Freiheit). Bei grossen Abständen bzw. kleinen Impulsüberträgen ist αs gross. Die Zunahme von αs bewirkt, dass unendlich viel Energie benötigt wird, um Quarks aus Hadronen herauszulösen. Dies hat die Folge, dass es günstiger ist ein neues Quark-Antiquark Paar zu erzeugen. Das erklärt, warum Quarks immer in Hadronen (Mesonen und Baryonen) gebunden sind und nie isoliert beobachtet werden können (Confinement).Wenn Kernmaterie stark komprimiert wird, steigen Energiedichte und Temperatur, und möglicherweise erfährt die Kernmaterie einen Phasenübergang zu einem Zustand der als Quark Gluon Plasma (QGP) bezeichnet wird. Das QGP ist ein Zustand der Materie, in dem das Confinement der Quarks und Gluonen aufgehoben ist (Deconfinement). Dieser Zustand ist gekennzeichnet durch ein quasi-freies Verhalten der Quarks und Gluonen. Quarks und Gluonen in Hadronen ein. Im heutigen Universum existiert das QGP höchstens noch im Zentrum von Neutronensternen und explodierenden schwarzen Löchern.

Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to cover the fascinating field of physics of relativistic heavy ions, mainly from the experimentalist's point of view. After the introductory chapter on quantum chromodynamics, basic properties of atomic nuclei, sources of relativistic nuclei, and typical detector set-ups are described in three subsequent chapters. Experimental facts on collisions of relativistic heavy ions are systematically presented in 15 consecutive chapters, starting from the simplest features like cross sections, multiplicities, and spectra of secondary particles and going to more involved characteristics like correlations, various relatively rare processes, and newly discovered features: collective flow, high pT suppression and jet quenching. Some entirely new topics are included, such as the difference between neutron and proton radii in nuclei, heavy hypernuclei, and electromagnetic effects on secondary particle spectra.Phenomenological approaches and related simple models are discussed in parallel with the presentation of experimental data. Near the end of the book, recent ideas about the new state of matter created in collisions of ultrarelativistic nuclei are discussed. In the final chapter, some predictions are given for nuclear collisions in the Large Hadron Collider (LHC), now in construction at the site of the European Organization for Nuclear Research (CERN), Geneva. Finally, the appendix gives us basic notions of relativistic kinematics, and lists the main international conferences related to this field. A concise reference book on physics of relativistic heavy ions, it shows the present status of this field.

Download or read book Melting Hadrons Boiling Quarks From Hagedorn Temperature to Ultra Relativistic Heavy Ion Collisions at CERN written by Johann Rafelski and published by Springer. This book was released on 2015-10-21 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Bor n 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.

Available in PDF, EPUB and Kindle. Book excerpt: Written primarily for researchers and graduate students who are new in this emerging field, this book develops the necessary tools so that readers can follow the latest advances in this subject. Readers are first guided to examine the basic informations on nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A good survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarised.

Download or read book An Introductory Course of Particle Physics written by Palash B. Pal and published by Taylor & Francis. This book was released on 2014-07-29 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: For graduate students unfamiliar with particle physics, An Introductory Course of Particle Physics teaches the basic techniques and fundamental theories related to the subject. It gives students the competence to work out various properties of fundamental particles, such as scattering cross-section and lifetime. The book also gives a lucid summary of the main ideas involved. In giving students a taste of fundamental interactions among elementary particles, the author does not assume any prior knowledge of quantum field theory. He presents a brief introduction that supplies students with the necessary tools without seriously getting into the nitty-gritty of quantum field theory, and then explores advanced topics in detail. The book then discusses group theory, and in this case the author assumes that students are familiar with the basic definitions and properties of a group, and even SU(2) and its representations. With this foundation established, he goes on to discuss representations of continuous groups bigger than SU(2) in detail. The material is presented at a level that M.Sc. and Ph.D. students can understand, with exercises throughout the text at points at which performing the exercises would be most beneficial. Anyone teaching a one-semester course will probably have to choose from the topics covered, because this text also contains advanced material that might not be covered within a semester due to lack of time. Thus it provides the teaching tool with the flexibility to customize the course to suit your needs.
Download or read book A Search for Displaced Leptons in the ATLAS Detector written by Lesya Horyn and published by Springer Nature. This book was released on 2022-02-07 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a search for long-lived particles decaying into displaced electrons and/or muons with large impact parameters. This signature provides unique sensitivity to the production of theoretical lepton-partners, sleptons. These particles are a feature of supersymmetric theories, which seek to address unanswered questions in nature. The signature searched for in this thesis is difficult to identify, and in fact, this is the first time it has been probed at the Large Hadron Collider (LHC). It covers a long-standing gap in coverage of possible new physics signatures. This thesis describes the special reconstruction and identification algorithms used to select leptons with large impact parameters and the details of the background estimation. The results are consistent with background, so limits on slepton masses and lifetimes in this model are calculated at 95% CL, drastically improving on the previous best limits from the Large Electron Positron Collider (LEP).
