Release Date: 2011-11-16
Genre: Science

The book provides theoretical and phenomenological insights on the structure of matter, presenting concepts and features of elementary particle physics and fundamental aspects of nuclear physics. Starting with the basics (nomenclature, classification, acceleration techniques, detection of elementary particles), the properties of fundamental interactions (electromagnetic, weak and strong) are introduced with a mathematical formalism suited to undergraduate students. Some experimental results (the discovery of neutral currents and of the W± and Z0 bosons; the quark structure observed using deep inelastic scattering experiments) show the necessity of an evolution of the formalism. This motivates a more detailed description of the weak and strong interactions, of the Standard Model of the microcosm with its experimental tests, and of the Higgs mechanism. The open problems in the Standard Model of the microcosm and macrocosm are presented at the end of the book.

From the Universe to the Elementary Particles

Author: Ulrich Ellwanger
Publisher: Springer Science & Business Media
ISBN: 9783642243752
Release Date: 2012-01-05
Genre: Science

In this book, the author leads the reader, step by step and without any advanced mathematics, to a clear understanding of the foundations of modern elementary particle physics and cosmology. He also addresses current and controversial questions on topics such as string theory. The book contains gentle introductions to the theories of special and general relativity, and also classical and quantum field theory. The essential aspects of these concepts are understood with the help of simple calculations; for example, the force of gravity as a consequence of the curvature of the space-time. Also treated are the Big Bang, dark matter and dark energy, as well as the presently known interactions of elementary particles: electrodynamics, the strong and the weak interactions including the Higgs boson. Finally, the book sketches as yet speculative theories: Grand Unification theories, supersymmetry, string theory and the idea of additional dimensions of space-time. Since no higher mathematical or physics expertise is required, the book is also suitable for college and university students at the beginning of their studies. Hobby astronomers and other science enthusiasts seeking a deeper insight than can be found in popular treatments will also appreciate this unique book.

Introduction to Particle and Astroparticle Physics

Author: Alessandro De Angelis
Publisher: Springer
ISBN: 9783319781815
Release Date: 2018-06-19
Genre: Science

This book introduces particle physics, astrophysics and cosmology. Starting from an experimental perspective, it provides a unified view of these fields that reflects the very rapid advances being made. This new edition has a number of improvements and has been updated to describe the recent discovery of gravitational waves and astrophysical neutrinos, which started the new era of multimessenger astrophysics; it also includes new results on the Higgs particle. Astroparticle and particle physics share a common problem: we still don’t have a description of the main ingredients of the Universe from the point of view of its energy budget. Addressing these fascinating issues, and offering a balanced introduction to particle and astroparticle physics that requires only a basic understanding of quantum and classical physics, this book is a valuable resource, particularly for advanced undergraduate students and for those embarking on graduate courses. It includes exercises that offer readers practical insights. It can be used equally well as a self-study book, a reference and a textbook.

Publisher: Springer-Verlag
ISBN: 9783642325793
Release Date: 2012-11-15
Genre: Science

Der aktuelle Wissensstand der Kern- und Elementarteilchenphysik hat eine wechselvolle Entstehungsgeschichte, oft gekennzeichnet durch schockierend neue Begriffsbildungen, die sich bis heute auch den Physik-Studierenden nur unter Mühen erschließen. Dieses Buch nutzt die kontroversen und zugleich lehrreichen Entwicklungsprozesse selber für den Zugang zu den schwierigen neuen Konzepten. Es macht verständlich, wie das physikalische Bild von den kleinsten Teilchen heute aussieht und warum es so und nicht anders entstanden ist: vom Nachweis der Existenz der Atome bis zum derzeitigen Standard-Modell der Elementarteilchenphysik, in einem ständigen Wechselspiel zwischen etablierten theoretischen Modellen, bestätigenden oder widersprechenden experimentellen Befunden, zuweilen umstrittenen neuen Begriffsbildungen, verbesserten Experimenten usw. - ein Prozess, der sicher auch künftig weiter geht. Leitschnur der Darstellung ist eine auch im Detail möglichst nachvollziehbare Argumentation. Physik-Studierende vor ihrem B.Sc.-Abschluss werden sich Kenntnisse über die subatomare Physik aneignen können, die zum Allgemeinwissen ihres Fachs zählen. Auch für Physik-Lehrende an Schulen oder Hochschulen dürfte diese neue Darstellung interessant sein. Die neue Auflage wurde auf den neuesten Wissenstand gebracht, insbesondere erste Ergebnisse vom LHC sind eingeflossen.

Teilchen und Kerne

Author: Bogdan Povh
Publisher: Springer-Verlag
ISBN: 9783642974755
Release Date: 2013-03-07
Genre: Science

Die Grundidee dieses einführenden Lehrbuchs besteht darin, eine einheitliche Darstellung von Kern- und Teilchenphysik aus experimenteller Sicht zu geben. Die Reduktion der komplex aufgebauten Materie der Atomkerne und Nukleonen auf wenige Grundbausteine und Wechselwirkungen ist seine erste Botschaft. Die Botschaft des zweiten Teils, der den Aufbau des Quarks über die Nukleonen zu den Kernen beschreibt, ist, daß Komplexität, die aus der Vielkörper-Wechselwirkung entsteht, immer mehr die Gesetzmäßigkeiten der zusammengesetzten Systeme bestimmt. Entstanden aus Vorlesungen an der Heidelberger Universität eignet sich dieses straff und klar abgefaßte, durch Übungsaufgaben ergänzte Lehrbuch gut als Begleittext zu einführenden Kursusvorlesungen an Hochschulen.

Einf hrung in die Elementarteilchenphysik

Publisher: VCH
ISBN: 3055016270
Release Date: 1996
Genre:

The fall of the Berlin Wall in 1989 and globalization have forced national history to yield place to European and global history. In medieval studies, Michael Borgolte has taken up the new challenge as no other German historian, encouraging the development of transcultural research on the Middle Ages. This volume includes several of his essays, but is intended to serve more as the basis for further research rather than to take stock of his work.

An Introduction to Relativistic Processes and the Standard Model of Electroweak Interactions

Author: Carlo M. Becchi
Publisher: Springer
ISBN: 9783319061306
Release Date: 2014-05-19
Genre: Science

This book offers a self-contained introduction to the theory of electroweak interactions based on the semi-classical approach to relativistic quantum field theory, with thorough discussion of key aspects of the field. The basic tools for the calculation of cross sections and decay rates in the context of relativistic quantum field theory are reviewed in a short, but complete and rigorous, presentation. Special attention is focused on relativistic scattering theory and on calculation of amplitude in the semi-classical approximation. The central part of the book is devoted to an illustration of the unified field theory of electromagnetic and weak interactions as a quantum field theory with spontaneously broken gauge invariance; particular emphasis is placed on experimental confirmations of the theory. The closing chapters address the most recent developments in electroweak phenomenology and provide an introduction to the theory and phenomenology of neutrino oscillations. In this 2nd edition the discussion of relativistic scattering processes in the semi-classical approximation has been revised and as a result intermediate results are now explicitly proven. Furthermore, the recent discovery of the Higgs boson is now taken into account throughout the book. In particular, the Higgs decay channel into a pair of photons, which has played a crucial role in the discovery, is discussed. As in the first edition, the accent is still on the semi-classical approximation. However, in view of the necessity of a discussion of H !, the authors give several indications about corrections to the semiclassical approximation. Violation of unitarity is discussed in more detail, including the dispersion relations as a tool for computing loop corrections; the above-mentioned Higgs decay channel is illustrated by means of a full one-loop calculation; and finally, loop effects on the production of unstable particles (such as the Z0 boson) are now discussed. Finally, the neutrino mass and oscillation analysis is updated taking into account the major achievements of the last years.

Particle Physics in the LHC Era

Author: Tony Weidberg
Publisher: Oxford University Press
ISBN: 9780198748557
Release Date: 2016-01-14
Genre:

This text gives an introduction to particle physics at a level accessible to advanced undergraduate students. It is based on lectures given to 4th year physics students over a number of years, and reflects the feedback from the students. The aim is to explain the theoretical and experimental basis of the Standard Model (SM) of Particle Physics with the simplest mathematical treatment possible. All the experimental discoveries that led to the understanding of the SM relied on particle detectors and most of them required advanced particle accelerators. A unique feature of this book is that it gives a serious introduction to the fundamental accelerator and detector physics, which is currently only available in advanced graduate textbooks. The mathematical tools that are required such as group theory are covered in one chapter. A modern treatment of the Dirac equation is given in which the free particle Dirac equation is seen as being equivalent to the Lorentz transformation. The idea of generating the SM interactions from fundamental gauge symmetries is explained. The core of the book covers the SM. The tools developed are used to explain its theoretical basis and a clear discussion is given of the critical experimental evidence which underpins it. A thorough account is given of quark flavour and neutrino oscillations based on published experimental results, including some from running experiments. A simple introduction to the Higgs sector of the SM is given. This explains the key idea of how spontaneous symmetry breaking can generate particle masses without violating the underlying gauge symmetry. A key feature of this book is that it gives an accessible explanation of the discovery of the Higgs boson, including the advanced statistical techniques required. The final chapter gives an introduction to LHC physics beyond the standard model and the techniques used in searches for new physics. There is an outline of the shortcomings of the SM and a discussion of possible solutions and future experiments to resolve these outstanding questions.

Collider Physics within the Standard Model

Author: Guido Altarelli
Publisher: Springer
ISBN: 9783319519203
Release Date: 2017-04-19
Genre: Science

This book is open access under a CC BY 4.0 license. With this graduate-level primer, the principles of the standard model of particle physics receive a particular skillful, personal and enduring exposition by one of the great contributors to the field. In 2013 the late Prof. Altarelli wrote: The discovery of the Higgs boson and the non-observation of new particles or exotic phenomena have made a big step towards completing the experimental confirmation of the standard model of fundamental particle interactions. It is thus a good moment for me to collect, update and improve my graduate lecture notes on quantum chromodynamics and the theory of electroweak interactions, with main focus on collider physics. I hope that these lectures can provide an introduction to the subject for the interested reader, assumed to be already familiar with quantum field theory and some basic facts in elementary particle physics as taught in undergraduate courses. “These lecture notes are a beautiful example of Guido’s unique pedagogical abilities and scientific vision”. From the Foreword by Gian Giudice

Relativistische Quantenmechanik

Author: Armin Wachter
Publisher: Springer-Verlag
ISBN: 9783540274841
Release Date: 2006-03-30
Genre: Science

- Welche Probleme tauchen in relativistischen Erweiterungen der Schrödinger-Theorie auf, insbesondere wenn man an der gewohnten Ein-Teilchen-Wahrscheinlichkeitsinterpretation festhält? - Inwieweit können diese Schwierigkeiten überwunden werden? - Worin besteht die physikalische Notwendigkeit von Quantenfeldtheorien? Viele Bücher geben auf solch fundamentale Verständnisfragen nur unzureichend Antwort, indem sie das relativistisch-quantenmechanische Ein-Teilchenkonzept zugunsten einer möglichst frühen Einführung der Feldquantisierung relativ schnell abhandeln oder ganz weglassen. Im Gegensatz dazu betont das vorliegende Lehrbuch gerade diesen Ein-Teilchenaspekt (relativistische Quantenmechanik ‚im engeren Sinne’), diskutiert die damit einhergehenden Probleme und motiviert somit auf physikalisch verständliche Weise die Notwendigkeit quantisierter Felder. Die ersten beiden Kapitel beschäftigen sich mit der ausführlichen Darlegung und Gegenüberstellung der Klein-Gordon- und Dirac-Theorie - immer mit Blick auf die nichtrelativistische Theorie. Im dritten Kapitel werden relativistische Streuprozesse behandelt und die Feynman-Regeln aus Propagatorverfahren heraus entwickelt. Dabei wird auch hier deutlich, warum man letztlich um eine quantenfeldtheoretische Begründung nicht herumkommt. Dieses Lehrbuch wendet sich an alle Studierenden der Physik, die an einer übersichtlich geordneten Darstellung der relativistischen Quantenmechanik ‚im engeren Sinne’ und deren Abgrenzung zu Quantenfeldtheorien interessiert sind.

Jenseits der Nanowelt

Publisher: Springer-Verlag
ISBN: 9783540266730
Release Date: 2005-12-05
Genre: Science

Dies ist eine hervorragende Einführung in die Teilchenphysik und ebenso ein Repetitorium für Studenten im Prüfungssemester und für Lehrer an Gymnasien. Der Autor, der als Forscher wesentliche Entwicklungen der Teilchenphysik begleitet hat und der als herausragender Lehrer gilt, wählt die Geschichte der Teilchenphysik als roten Faden. Die Begriffe und die Theorien werden in großer Klarheit präsentiert, und die Experimente werden herangezogen, um Erfolg und Misserfolg auf dem Weg zum Standardmodell zu illustrieren. Der mathematische Apparat wird klein gehalten, so dass das Buch auch den interessierten Laien in seinen Bann ziehen wird.

Particles and Nuclei

Author: Bogdan Povh
Publisher: Springer
ISBN: 9783662463215
Release Date: 2015-06-15
Genre: Science

This well-known introductory textbook gives a uniform presentation of nuclear and particle physics from an experimental point of view. The first part, Analysis, is devoted to disentangling the substructure of matter. This part shows that experiments designed to uncover the substructures of nuclei and nucleons have a similar conceptual basis, and lead to the present picture of all matter being constructed from a small number of elementary building blocks and a small number of fundamental interactions. The second part, Synthesis, shows how the elementary particles may be combined to build hadrons and nuclei. The fundamental interactions, which are responsible for the forces in all systems, become less and less evident in increasingly complex systems. Such systems are in fact dominated by many-body phenomena. A section on neutrino oscillations and one on nuclear matter at high temperatures bridge the field of "nuclear and particle physics" and "modem astrophysics and cosmology.“p> The seventh revised and extended edition includes new material, in particular the experimental verification of the Higgs particle at the LHC, recent results in neutrino physics, the violation of CP-symmetry in the decay of neutral B-mesons, the experimental investigations of the nucleon's spin structure and outstanding results of the HERA experiments in deep-inelastic electron- and positron-proton scattering. The concise text is based on lectures held at the University of Heidelberg and includes numerous exercises with worked answers. It has been translated into several languages and has become a standard reference for advanced undergraduate and graduate courses.
