Supersymmetric Grand Unified Theories by Stuart Raby Pdf

These course-tested lectures provide a technical introduction to Supersymmetric Grand Unified Theories (SUSY GUTs), as well as a personal view on the topic by one of the pioneers in the field. While the Standard Model of Particle Physics is incredibly successful in describing the known universe it is, nevertheless, an incomplete theory with many free parameters and open issues. An elegant solution to all of these quandaries is the proposed theory of SUSY GUTs. In a GUT, quarks and leptons are related in a simple way by the unifying symmetry and their electric charges are quantized, further the relative strength of the strong, weak and electromagnetic forces are predicted. SUSY GUTs additionally provide a framework for understanding particle masses and offer candidates for dark matter. Finally, with the extension of SUSY GUTs to string theory, a quantum-mechanically consistent unification of the four known forces (including gravity) is obtained. The book is organized in three sections: the first section contains a brief introduction to the Standard Model, supersymmetry and the Minimal Supersymmetric Standard Model. Then SUSY GUTs in four space-time dimensions are introduced and reviewed. In addition, the cosmological issues concerning SUSY GUTs are discussed. Then the requirements for embedding a 4D SUSY GUT into higher-dimensional theories including gravity (i.e. String Theory) are investigated. Accordingly, section two of the course is devoted to discussing the so-called Orbifold GUTs and how in turn they solve some of the technical problems of 4D SUSY GUTs. Orbifold GUTs introduce a new set of open issues, which are then resolved in the third section in which it is shown how to embed Orbifold GUTs into the E(8) x E(8) Heterotic String in 10 space-time dimensions.

Supersymmetry and String Theory by Michael Dine Pdf

The past decade has witnessed dramatic developments in the field of theoretical physics. This book is a comprehensive introduction to these recent developments. It contains a review of the Standard Model, covering non-perturbative topics, and a discussion of grand unified theories and magnetic monopoles. It introduces the basics of supersymmetry and its phenomenology, and includes dynamics, dynamical supersymmetry breaking, and electric-magnetic duality. The book then covers general relativity and the big bang theory, and the basic issues in inflationary cosmologies before discussing the spectra of known string theories and the features of their interactions. The book also includes brief introductions to technicolor, large extra dimensions, and the Randall-Sundrum theory of warped spaces. This will be of great interest to graduates and researchers in the fields of particle theory, string theory, astrophysics and cosmology. The book contains several problems, and password protected solutions will be available to lecturers at www.cambridge.org/9780521858410.

Not Even Wrong by Peter Woit Pdf

Not Even Wrong is a fascinating exploration of our attempts to come to grips with perhaps the most intellectually demanding puzzle of all: how does the universe work at its most fundamnetal level? The book begins with an historical survey of the experimental and theoretical developments that led to the creation of the phenomenally successful 'Standard Model' of particle physics around 1975. Despite its successes, the Standard Model does not answer all the key questions and physicists continuing search for answers led to the development of superstring theory. However, after twenty years, superstring theory has failed to advance beyond the Standard Model. The absence of experimental evidence is at the core of this controversial situation which means that it is impossible to prove that superstring theory is either right or wrong. To date, only the arguments of the theory's advocates have received much publicity. Not Even Wrong provides readers with another side of the story.

A Brief History of String Theory by Dean Rickles Pdf

During its forty year lifespan, string theory has always had the power to divide, being called both a 'theory of everything' and a 'theory of nothing'. Critics have even questioned whether it qualifies as a scientific theory at all. This book adopts an objective stance, standing back from the question of the truth or falsity of string theory and instead focusing on how it came to be and how it came to occupy its present position in physics. An unexpectedly rich history is revealed, with deep connections to our most well-established physical theories. Fully self-contained and written in a lively fashion, the book will appeal to a wide variety of readers from novice to specialist.

New Approaches Towards a Grand Unified Theory by Ray Munroe Pdf

This book is a serious effort to bridge the gap between Particle Physics and String Theory, and to unify the four known fundamental forces of Physics: Gravitation, Electromagnetism, and the Strong and Weak Nuclear Forces; although it uses ideas from unexpected branches of Physics.

String Theory, Quantum Gravity And The Unification Of The Fundamental Interactions - Proceedings Of The Conference by Massimo Bianchi,Enzo Marinari,F Fucito,Augusto Sagnotti Pdf

String theory is the candidate for the unification of all fundamental interactions including gravity. In the past few years this active field of research has developed very rapidly and in several different directions. The aim of the conference is to give an overview of the status of the art in string theory through the contributions of the major experts in this field. The main topics include: string unification and effective Lagrangians, N=2 string theories, 2-d quantum gravity, stringy black holes, topological field theory, conformal field theories, strings and quantum field theory.

Why String Theory? by Joseph Conlon Pdf

Physics World's 'Book of the Year' for 2016 An Entertaining and Enlightening Guide to the Who, What, and Why of String Theory, now also available in an updated reflowable electronic format compatible with mobile devices and e-readers. During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering a highly readable and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics. The author, a theoretical physics professor at the University of Oxford and a leading string theorist, explains what string theory is and where it originated. He describes how string theory fits into physics and why so many physicists and mathematicians find it appealing when working on topics from M-theory to monsters and from cosmology to superconductors.

The End Of Physics by David Lindley Pdf

The author presents a history of the attempts to find the final "theory of everything," gives a forceful argument that one can never be found, and a warning that the compromises necessary to produce a final theory may well undermine the rules of doing good science. At the heart of the story is the rise of the particle physicists and their attempts to reach far out into the cosmos for a unifying theory. Unable to subject their findings and theories to experimental scrutiny, they have moved into a world governed entirely by mathematical and highly speculative theories, none of which can be empirically verified. "Does physics then become a branch of aesthetics?" Lindley asks. For an opposing viewpoint, see Stephen Weinberg's Dreams of a Final Theory. Annotation copyright by Book News, Inc., Portland, OR

Superstrings by P. C. W. Davies,Julian Brown Pdf

Superstring theory is one of the most exciting and actively pursued branches of physics today. The far-reaching claims made for this theory would, if correct, provide the much sought-after Theory of Everything, the unification of physics. It would enable the fundamental building blocks of matter to be identified and amalgamated in a common description, with a unified theory of all the forces of nature. This book explains the theory for laymen, in an introduction to the subject which originated in the BBC Radio programme, Desperately Seeking Superstrings. A clear, concise, non-mathematical explanation of the theory and its profound implications is followed by transcripts of interviews with all the most important physicists involved in its development. Superstrings makes a fascinating topic at the forefront of modern scientific research accessible to physicists, philosophers and general readers alike.
