Book Description
PASCOS is an interdisciplinary symposium on the interface of of Particle physics, String theory and Cosmology. Over the past two decades these three disciplines have increasingly become closer. Historically there was always a strong overlap between particle physics and cosmology. This connection has become even stronger with the realization that some of the fundamental issues in cosmology such as the presence of dark matter and dark energy may possibly find a resolution only via new theories of particle physics. At the same time string theory has begun to play an increasingly important role in particle physics as a possible framework for building unified models of particle interaction including gravity. In recent years we have seen an increasing overlap between cosmology and string theory and currently the area of string cosmology is one of the most active fields of research. PASCOS 2005 aimed to provide coherent discussions of recent developments on the interface of the three disciplines and also on their interconnections. In particular, superstring aspects in low energy particle theory (SUSY) and cosmological applications (moduli stabilization) are extensively covered in this volume. Topics include dark matter and dark energy, baryogenesis, flavor and CP violation, neutrino physics, supersymmetry and extra dimensions, flux compactification, string model building, as well as brane cosmology.

Book Description
This unique book gives a modern account of particle physics and gravity based on supersymmetry and supergravity, two of the most significant developments in theoretical physics since general relativity. The book begins with a brief overview of the history of unification and then goes into a detailed exposition of both fundamental and phenomenological topics. The topics in fundamental physics include Einstein gravity, Yang–Mills theory, anomalies, the standard model, supersymmetry and supergravity, and the construction of supergravity couplings with matter and gauge fields, as well as computational techniques for SO(10) couplings. The topics of phenomenological interest include implications of supergravity models at colliders, CP violation, and proton stability, as well as topics in cosmology such as inflation, leptogenesis, baryogenesis, and dark matter. The book is intended for graduate students and researchers seeking to master the techniques for building grand unified models.

Book Description
This thesis presents a study on phenomenology of beyond the Standard Model (SM) in the context of extensions of supersymmetric realisations. This extended framework allows us to accommodate viable dark matter (DM) candidates which the SM do not have, and it offers a unified gauge structure for all three nuclear forces. With this motivation, we investigated two possible extensions of MSSM and their predictabilities in future collider experiments. First, we presented an extension of MSSM via vector-like (VL) supermultiplets which can provide new annihilation channels for dark matter. We investigate a simple extension with two VL pairs of weak doublets (lepton and down-type quark) and a pair of VL-neutrino singlets. Both neutralino and sneutrinos can emerge as viable DM candidates in such a framework. A complete analysis has been conducted on the DM. Furthermore, we investigate specific collider signatures that such construction can bring and demonstrate the enhanced production of events fortified with tau leptons. Secondly, we investigated U(1) extensions of the MSSM framework within E6 gauge structure by conducting a detailed analysis of the parameter space that can emerge through a variety of U(1)' charge structures. Such a scenario predicts two DM candidates, neutralino and sneutrino. We presented a detailed analysis of low energy and cosmological observables. It is also vital to present the specific signatures that such gauge structure can bring into collider experiments. A heavy Z' boson is one of the identifying features of such a framework. We investigated possible loopholes in analyses where we observed that Z' mass bounds can be relaxed up to 300 GeV by changing the boundary conditions on the gauge couplings. We presented possible leptophobic scenarios which can be observed through supersymmetric cascade decays up to $7\sigma$ statistical significance at $ \sqrt{s}=14 $~TeV with 3 ab-1 integrated luminosity. Finally, we revisited the current LHC bounds on supersymmetric particles in the light of theoretical uncertainties and studied high luminosity predictions. We investigated the effects of these uncertainties on gluino, squark mass limits and on coupling sensitivity of simplified s-channel DM models.

Book Description
The Physical World offers a grand vision of the essential unity of physics that will enable the reader to see the world through the eyes of a physicist and understand their thinking. The text follows Einstein's dictum that 'explanations should be made as simple as possible, but no simpler', to give an honest account of how modern physicists understand their subject, including the shortcomings of current theory. The result is an up-to-date and engaging portrait of physics that contains concise derivations of the important results in a style where every step in a derivation is clearly explained, so that anyone with the appropriate mathematical skills will find the text easy to digest. It is over half a century since The Feynman Lectures in Physics were published. A new authoritative account of fundamental physics covering all branches of the subject is now well overdue. The Physical World has been written to satisfy this need. The book concentrates on the conceptual principles of each branch of physics and shows how they fit together to form a coherent whole. Emphasis is placed on the use of variational principles in physics, and in particular the principle of least action, an approach that lies at the heart of modern theoretical physics, but has been neglected in most introductory accounts of the subject.
