String theory represents a major dream of theoretical physicists — a description of all forces and matter in one mathematical picture. But after countless papers, conferences and dry-erase. see also Braneworlds, Compactifications, Cosmology, Neutrinos. reviews.

We study different phenomenological aspects of compact, D = 4, N = 1 Type IIB orientifolds considered as models for unification of the standard model and gravity. We discuss the structure of the compactification, string and unification scales depending on the different possible D-brane by: 8 M-theory and string duality Low-energy effective actions S-duality M-theory M-theory dualities 9 String geometry Orbifolds Calabi-Yau manifolds: mathematical properties Examples of Calabi-Yau manifolds Calabi-Yau compactifications of the heterotic string
These notes provide a hopefully pedagogic introduction to Born-Infeld theory and some of its uses in String/M-Theory from the perspective of some-one interested in spacetime geometry. Causality and the consequences of having both the open string and closed string metric are stressed. M-theory scenarios Recently Ho~ava and Witten proposed that the strong coupling limit of E8 x E8 heterotic string theory can be described by dimensional SUGRA on a manifold with boundary where the two E8 gauge multiplets are restricted to the two dimensional boundaries respectively (M-theory) .

Download Citation | Some phenomenological aspects of Type IIB/F-theory string compactifications | This article is the PhD thesis of the author. It is focused on Type II compactifications because. This is first of a series of notes on the geometry of String Theory compactifications.
The space-time in String Theory 1 2 is often described by means of a mathematical object called manifold lds are very important objects from the mathematical and. If the address matches an existing account you will receive an email with instructions to reset your password.
It introduces the basics of perturbative string theory, world-sheet supersymmetry, space-time supersymmetry, conformal field theory and the heterotic string, before describing modern developments, including D-branes, string dualities and M-theory.
It then covers string geometry and flux compactifications, applications to cosmology and particle Cited by: In this thesis we study compactifications of type II string theories and M-theory to four dimensions.
We construct the four-dimensional N=2 supergravities that arise from compactifications of type. Phenomenological aspects of M–theory 4 depicted in ﬁgure 1. In this context, the true fundamental th eory of nature should have some nonperturbative realization. However, at present all we know about this more basic theory, are its perturbative string limits.
Therefore, Cited by: 4. Idea. String phenomenology is phenomenology in particle physics and cosmology based on models that are derived or at least motivated from string theory (as effective QFTs from string vacua). Broadly speaking, string phenomenology refers to investigations of the connection of string theory to experimentally observed restrictively it refers to constructions of string theory vacua.
In string theory the one-dimensional trajectory of a particle in spacetime is replaced by a two-dimensional orbit of a string. Such strings can be of any size, but under ordinary circumstances they are quite tiny, a value determined by comparing the predictions of the theory for.
String theory is one of the most exciting and challenging areas of modern theoretical physics. This book guides the reader from the basics of string theory to recent developments. It introduces the basics of perturbative string theory, world-sheet supersymmetry, space-time supersymmetry, conformal field theory and the heterotic string, before describing modern 4/5(2).
M-theory is the only model that has all the properties we think the final theory ought to have, and it is the theory upon which much of our later discussion is based. M-theory is not a theory in the usual sense. Buy String Theory and M-Theory: A Modern Introduction 1 by Becker, Katrin, Becker, Melanie, Schwarz, John H.

It tries to reconcile the gap between the conception of our universe based on its four observable dimensions with the ten, eleven, or twenty-six dimensions which theoretical equations lead us to suppose the universe is made with.
of Amsterdam. We have also drawn on some ideas from the books String Theory and M-Theory (Becker, Becker and Schwarz), Introduction to String Theory (Polchinski), String Theory in a Nutshell (McMahon) and Superstring Theory (Green, Schwarz and Witten), along with the lecture notes of David Tong, sometimes word-for-word.
Although the mathematical constructions used in string theory have changed considerably since this book was published init could still serve as an introduction to some of the mathematics of string theory, although the subject currently is dominated by M-theory.4/5(1).
In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called describes how these strings propagate through space and interact with each other.
On distance scales larger than the string scale, a string looks just like an ordinary particle, with its mass, charge, and other properties. M-theory on manifolds of G_2 holonomy: the first twenty years by M.

Many of the topics in this book are outgrowths of the spectacular new understanding of duality in string theory which emerged around They include the AdS/CFT correspondence and its relation to holography, the matrix theory formulation of M theory, the structure of black holes in string theory, the structure of D-branes and M-branes, and.About this book Introduction Called by some, "the theory of everything", superstrings may solve a problem which has eluded physicists for the past 50 years - the final unification of the two great theories of the twentieth century, general relativity and quantum field theory.String theory is speculative science.
There is no experimental evidence that string theory is the correct description of our world and scant hope that hard evidence will arise in the near future.
Moreover, string theory is very much a work in progress and certain aspects of the theory are far from understood. Unresolved issues abound andFile Size: 1MB.
