Book Synopsis Dark Matter, Inflation, and Baryogenesis in the Higgs Era by : Robert Hogan
Download or read book Dark Matter, Inflation, and Baryogenesis in the Higgs Era written by Robert Hogan and published by . This book was released on 2016 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the successes of particle physics and cosmology there are still some big unanswered questions. We still do not have a complete understanding of the nature of dark matter, the origin of the baryon asymmetry of the Universe, and the mechanism behind cosmic inflation. In this thesis we will address these problems by proposing minimal extensions of the Standard Model of particle physics in which the recently discovered Higgs boson often plays a central role. The aim is to provide an economical explanation for these phenomena by introducing as few new ingredients as possible. As a results these models are easily interpretable and testable with complementary particle physics and cosmological observations.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model of particle physics has been strengthened by the recent discovery of the long-awaited Higgs boson. The standard cosmological model has met the challenge of the high precision observations in comology and astroparticle physics. However these two standard models face both several theoretical issues, such as the naturalness problem in the Higgs sector of the Standard Model, as well as observational issues, in particular the fact that an unknown kind of matter called Dark Matter accounts for the majority of the matter content in our Universe. Attempts to solve such problems have led to the development of New Physics models during the last decades. Supersymmetry is one such model which addresses the fine-tuning problem in the Higgs sector and provides viable Dark Matter candidates. Current high energy and high precision experiments give many new opportunities to probe the supersymmetric models. It is in this context that this thesis is written. Considering the Minimal Supersymmetric Standard Model (MSSM), the simplest supersymmetric extension of the Standard Model of particle physics, and its conventional Dark Matter candidate, the neutralino, it is shown that collider constraints could provide informations on the very early Universe at the inflation area. It is also demonstrated that the Indirect Detection of Dark Matter, despite several drawbacks, can be a powerful technique to probe supersymmetric Dark Matter models. Beyond the MSSM it is shown that unique characteristics of the Dark Matter candidate in the NMSSM could be probed at colliders. The study of a supersymmetric model with an extended gauge symmetry, the UMSSM, is also developed. The features of another Dark Matter candidate of this model, the Right-Handed sneutrino, are analysed. More general constraints such as those coming from low energy observables are finally considered in this model.

This book was released on 2017 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compelling astrophysical evidence for dark matter on one hand and the experimental evidence for neutrino masses on the other, demands modifications beyond the Standard Model. Therefore, building new models by extending the symmetries and particle content of the Standard Model is being pursued to remedy these problems. In this thesis, various models along with their predictions are presented. First, a gauge SU(2)N extension of the Standard Model, under which all of the Standard Model particles are singlet is introduced. The inverse seesaw mechanism is implemented for neutrino mass, with the new gauge boson as a dark matter candidate. The second paper is a gauge B-L extension of the Standard Model which breaks down to Z3, and it includes a long-lived dark matter candidate. The next model assumes that leptons do not couple directly to Higgs, and one loop mass generation is considered with important consequences, including Higgs decay, muon anomalous magnetic moment, etc. We then look at a U(1) gauge extension of the supersymmetric Standard Model, which has no [mu] term, and the Higgs boson's mass supersymmetric constraint is relaxed. The next model is a gauge B-L extension of the Standard Model with radiative seesaw neutrino mass and multipartite dark matter. We then consider another gauge U(1) extension under which quarks and leptons of each family may transform differently, while flavor-changing interactions are suitably suppressed. The next paper has an unbroken gauge SU(2) symmetry, which becomes confining at keV scale. We discuss the cosmological constraints and the implications for future e +e- colliders. Finally, an alternative left-right model is proposed with an automatic residual Z 2 × Z3 symmetry, such that dark matter has two components, i.e., one Dirac fermion and one complex scalar.

Book Synopsis Implications for Dark Matter from Supersymmetric Axion Cosmology by : Raymond Tung Ming Co
Download or read book Implications for Dark Matter from Supersymmetric Axion Cosmology written by Raymond Tung Ming Co and published by . This book was released on 2017 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the Higgs boson discovery at the Large Hadron Collider, the Standard Model continues to prove its success in particle physics and cosmology. Despite its remarkable achievements, the Standard Model remains incomplete owing to theoretical difficulties such as the hierarchy problem, the strong charge-parity (CP) problem, and the lack of dark matter candidates. Supersymmetry has been proposed to solve the hierarchy problem by protecting the Higgs mass from radiative quantum corrections. In supersymmetry, the lightest supersymmetric particles are well-motivated candidates for dark matter. When the Peccei-Quinn symmetry is evoked to solve the strong CP problem, the axion becomes another viable candidate. One can attempt to simultaneously solve the aforementioned problems with supersymmetric axion theories. Nonetheless, the scalar superpartner of the axion, the saxion, significantly changes the conventional picture of cosmology and dark matter production. During inflation, a potential for saxions is induced and displaces the saxion field value away from the minimum of the potential today. This results in a saxion condensate that dominates the energy density of the Universe -- a non-standard matter-dominated epoch. The saxion subsequently decays to the particles in the thermal bath, generating a large amount of entropy and diluting the dark matter abundance. The saxion hence plays a crucial role in the cosmological evolution of dark matter. We focus on the cases where dark matter is the axion from the misalignment mechanism, or the axino/gravitino lightest supersymmetric particle that is populated from the thermal scattering and freeze-in processes. The former case allows the Peccei-Quinn symmetry and grand unification to be of the same origin, whereas the latter case allows a high reheat temperature after inflation, solving the axino/gravitino problems. We will also discuss interesting phenomenology for this class of theories such as dark radiation and displaced vertices at colliders.

Available in PDF, EPUB and Kindle. Book excerpt: In the field of particle and astrophysics, one of the major unresolved problems is to understand the nature and properties of dark matter, which constitutes almost 80% of the matter content of the universe. This book gives a pedagogical introduction to the field of dark matter in general, and in particular to the model building perspective. Starting from the evidence and need for dark matter, it goes into the deeper understanding of how to accommodate a dark matter candidate in a particle physics model. This book focuses on teaching the basic tools for model building of dark matter, starting from the easiest to gradually the difficult one. Although there are plenty of dark matter models available in the literature, this book concentrates on the important ones. This book aims to motivate the reader to propose a new dark matter model complying with all observational constraints.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Download or read book Cosmological Inflation, Dark Matter and Dark Energy written by Kazuharu Bamba and published by MDPI. This book was released on 2019-11-14 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various cosmological observations support not only cosmological inflation in the early universe, which is also known as exponential cosmic expansion, but also that the expansion of the late-time universe is accelerating. To explain this phenomenon, the existence of dark energy is proposed. In addition, according to the rotation curve of galaxies, the existence of dark matter, which does not shine, is also suggested. If primordial gravitational waves are detected in the future, the mechanism for realizing inflation can be revealed. Moreover, there exist two main candidates for dark matter. The first is a new particle, the existence of which is predicted in particle physics. The second is an astrophysical object which is not found by electromagnetic waves. Furthermore, there are two representative approaches to account for the accelerated expansion of the current universe. One is to assume the unknown dark energy in general relativity. The other is to extend the gravity theory to large scales. Investigation of the origins of inflation, dark matter, and dark energy is one of the most fundamental problems in modern physics and cosmology. The purpose of this book is to explore the physics and cosmology of inflation, dark matter, and dark energy.
Book Synopsis Light Scalar Fields in a Dark Universe by : Gabriel Zsembinszki
Download or read book Light Scalar Fields in a Dark Universe written by Gabriel Zsembinszki and published by LAP Lambert Academic Publishing. This book was released on 2014-04 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most successful scientific theory today about the origin and evolution of the universe is known as the standard Big Bang model, which is one of the most ambitious intellectual constructions of the humanity. It is based on two consolidated branches of theoretical physics, namely, the theory of General Relativity and the Standard Model of particle physics, and is able to make robust predictions, some of them being already confirmed by very precise observations. However, this model is not able to explain some questions raised by observational evidence, such as early inflation of the universe, dark matter and dark energy. This book makes an overview of some of the features of the standard cosmology, and also includes a few original models proposed to solve some of the shortcomings of the standard cosmology, as possible extensions of the Big Bang model. The models, published as articles in scientific journals, introduce new symmetries, fields and particles in order to explain inflation, dark energy and dark matter, separately or in a unified description. The book is addressed especially to PhD students, but also to anyone who is interested in cosmology and astroparticle theory.
Book Synopsis Perspectives On Supersymmetry by : Gordon Kane
Download or read book Perspectives On Supersymmetry written by Gordon Kane and published by World Scientific. This book was released on 1998-07-03 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supersymmetry is at an exciting stage of development. It extends the Standard Model of particle physics into a more powerful theory that both explains more and allows more questions to be addressed. Most important, it opens a window for studying and testing fundamental theories at the Planck scale. Experimentally we are finally entering the intensity and energy regions where superpartners are likely to be detected, and then studied. There has been progress in understanding the remarkable physics implications of supersymmetry, including the derivation of the Higgs mechanism, the unification of the Standard Model forces, cosmological connections such as a candidate for the cold dark matter of the universe and the scalar fields that drive inflation and their potential, the relationship to Planck scale theories, and more.While there are a number of reviews and books where the mathematical structure and uses of supersymmetry can be learned, there are few where the particle physics is the main focus. This book fills that gap. It begins with an excellent pedagogical introduction to the physics and methods and formalism of supersymmetry, by S Martin, which is accessible to anyone with a basic knowledge of the Standard Model of particle physics. Next is an overview of open questions by K Dienes and C Kolda, followed by chapters on topics ranging from how to detect superpartners to connections with Planck scale theories, by leading experts.This invaluable book will allow any interested physicist to understand the coming experimental and theoretical progress in supersymmetry, and will also help students and workers to quickly learn new aspects of supersymmetry they want to pursue.
Book Synopsis Journeys Beyond the Standard Model by : Jessica L. Goodman
Download or read book Journeys Beyond the Standard Model written by Jessica L. Goodman and published by . This book was released on 2013 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis attempts to address two outstanding issues in the Standard Model of particle physics. The first of these two has to do with the lack of a viable dark matter candidate in the Standard Model. Many recent experimental results hint at the possibility of a light dark matter particle. If it is light enough, one may consider producing these particles at colliders. Parts of this thesis considers effective theories of dark matter as a way to develop a language to compare collider searches for dark matter to direct and indirect detection experiments. The second of these two issues explores the more aesthetic problem of the gauge hierarchy through construction of supersymmetry breaking models. In the first set of models, we construct UV completions of O'Raifeartaigh-like models which spontaneously break R symmetry. In the final chapter, we construct a R symmetric GMSB model in which we use Seiberg dynamics to generate supersoft Dirac gaugino masses.
Book Synopsis Supersymmetric Dark Matter in the NMSSM and E6SSM by : Sophie Underwood
Download or read book Supersymmetric Dark Matter in the NMSSM and E6SSM written by Sophie Underwood and published by . This book was released on 2016 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supersymmetric extensions of the standard model may resolve the outstanding dark matter problem by producing viable dark matter candidates, including a stable weakly interacting particle called a neutralino. The next-to-minimal supersymmetric standard model (NMSSM) is first explored with a scan of the parameter space for neutralino-hadron scattering using an updated value for the strange quark sigma commutator. This is followed by an extensive exploration of the parameter space of the E6-inspired supersymmetric standard model (E6SSM). It is demonstrated that this model still provides neutralino dark matter candidates that may be detected in the near-future by upcoming experiments, despite tightening experimental constraints.
