Download or read book Chiral Four Dimensional Heterotic String Vacua from Covariant Lattices written by Florian Beye and published by Springer. This book was released on 2016-11-09 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is placed at the interface between string theory and elementary particle physics and shows novel results in the search for a heterotic string vacuum that reproduces those matter particles and interactions observed in our universe. The author provides a systematic classification of potentially realistic heterotic covariant lattice vacua, which possess a lower number of moduli fields when compared to conventional compactification methods, by means of number theoretical methods. These methods, while well known to the mathematics community, have not yet found many applications to physics. They are introduced to the degree necessary to understand the computations carried out throughout this work. Furthermore, explicit covariant lattice models with particularly interesting properties are analyzed in detail. Finally, new light is shed on the relation between covariant lattice models and asymmetric orbifold compactifications, the result being a concrete correspondence between certain types of asymmetric orbifolds and those classified covariant lattices.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a detailed guide on the journey towards the minimal supersymmetric standard model down the orbifold road. It takes the viewpoint that the chirality of matter fermions is an essential aspect that orbifold compactification allows to derive from higher-dimensional string theories in a straightforward manner. Halfway between textbook and tutorial review, the book is intended for the graduate student and particle phenomenologist wishing to get acquainted with this field.
Download or read book Superstrings written by P. C. W. Davies and published by Cambridge University Press. This book was released on 1992-07-31 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book A Brief History of String Theory written by Dean Rickles and published by Springer Science & Business Media. This book was released on 2014-02-18 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Orbifolds and Stringy Topology written by Alejandro Adem and published by Cambridge University Press. This book was released on 2007-05-31 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the theory of orbifolds from a modern perspective, combining techniques from geometry, algebraic topology and algebraic geometry. One of the main motivations, and a major source of examples, is string theory, where orbifolds play an important role. The subject is first developed following the classical description analogous to manifold theory, after which the book branches out to include the useful description of orbifolds provided by groupoids, as well as many examples in the context of algebraic geometry. Classical invariants such as de Rham cohomology and bundle theory are developed, a careful study of orbifold morphisms is provided, and the topic of orbifold K-theory is covered. The heart of this book, however, is a detailed description of the Chen-Ruan cohomology, which introduces a product for orbifolds and has had significant impact. The final chapter includes explicit computations for a number of interesting examples.

Download or read book Introduction to Superstring Theory written by Elias Kiritsis and published by Cornell University Press. This book was released on 1998-01 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: String Theory, now almost 30 years of age, was partly forgotten but came back to the forefront of theoretical particle physics in 1984. In this book, based on lectures by the author at the K.U.Leuven and at the University of Padova, Elias Kiritsis takes the reader through the developments of the last 15 years: conformal field theory, the various superstrings and their spectra, compactifications, and the effective description of low energy degrees of freedom. It ends by showing a glimpse of the most recent developments, dualities of strings and higher dimensional objects, that influence both traditional field theory and present day mathematics.
