Book excerpt: The Standard Model of Particle Physics has been verified to unprecedented precision in the last few decades. However there are still phenomena in nature which cannot be explained, and as such new theories will be required. Since terrestrial experiments are limited in both the energy and precision that can be probed, new methods are required to search for signs of physics beyond the Standard Model. In this dissertation, I demonstrate how these theories can be probed by searching for remnants of their effects in the early Universe. In particular I focus on three possible extensions of the Standard Model: the addition of massive neutral particles as dark matter, the addition of charged massive particles, and the existence of higher dimensions. For each new model, I review the existing experimental bounds and the potential for discovering new physics in the next generation of experiments. For dark matter, I introduce six simple models which I have developed, and which involve a minimum amount of new physics, as well as reviewing one existing model of dark matter. For each model I calculate the latest constraints from astrophysics experiments, nuclear recoil experiments, and collider experiments. I also provide motivations for studying sub-GeV mass dark matter, and propose the possibility of searching for light WIMPs in the decay of B-mesons and other heavy particles. For charged massive relics, I introduce and review the recently proposed model of catalyzed Big Bang nucleosynthesis. In particular I review the production of Li6 by this mechanism, and calculate the abundance of Li7 after destruction of Be7 by charged relics. The result is that for certain natural relics CBBN is capable of removing tensions between the predicted and observed Li6 and Li7 abundances which are present in the standard model of BBN. For extra dimensions, I review the constraints on the ADD model from both astrophysics and collider experiments. I then calculate the constraints on this model from.

Available in PDF, EPUB and Kindle. Book excerpt: Physics and astrophysics came to dark matter through many different routes, finally accepting it, but often with some distaste. It has been noticed that the existence of dark matter is yet another displacement of humans from the centre of the Universe: not only do our planet and our sun have no central position in the Universe, not only are humans just animals (although with a 'specialized' central nervous system), but even the material of which we are made is only a marginal component of the cosmic substance! If this is the right attitude to take, scientists feeling distaste for dark matter are much like Galileo Galilei's colleagues who refused to look through the telescope to watch the Medici planets. Nevertheless, astronomers, when required to take a ballot in favour of some cosmological model, often still vote for 'pure baryonic' with substantial majorities, although most cosmologists assume that a 'cold' component of dark matter plays a role in producing the world as we observe it. Among the many subjects covered by the book, particular emphasis was given to 1) summarizing the current status of the observations both of the distribution of the nearby galaxies and of the evolution of more distant galaxies; 2) advanced statistical techniques for quantifying structure in galaxy redshift and peculiar velocity surveys; 3) the art of cosmic inflation and models for dark matter candidates, and their implications for cosmic microwave background observations; 4) implications of cold dark matter variants for large scale structure, as worked out both by quasi-linear techniques and by fully nonlinear simulations; and 5) Eulerian and Lagrangian approximations for treating the nonlinear dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: This book is written from the viewpoint that a deep connection exists between cosmology and particle physics. It presents the results and ideas on both the homogeneous and isotropic Universe at the hot stage of its evolution and in later stages. The main chapters describe in a systematic and pedagogical way established facts and concepts on the early and the present Universe. The comprehensive treatment, hence, serves as a modern introduction to this rapidly developing field of science. To help in reading the chapters without having to constantly consult other texts, essential materials from General Relativity and the theory of elementary particles are collected in the appendices. Various hypotheses dealing with unsolved problems of cosmology, and often alternative to each other, are discussed at a more advanced level. These concern dark matter, dark energy, matter-antimatter asymmetry, etc. Particle physics and cosmology underwent rapid development between the first and the second editions of this book. In the second edition, many chapters and sections have been revised, and numerical values of particle physics and cosmological parameters have been updated. --

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use semi-analytical models and cosmological hydrodynamic simulations to derive the imprints of dark matter physics on the first generation of stars, black holes and galaxies, which, combined with observational data, place constraints on the properties of dark matter. Inspired by the recent detection of gravitational waves, we further investigate the gravitational waves of the first star remnants as a promising probe for early star/structure formation and dark matter physics. Our results indicate that although the first stars only make up a tiny fraction (~ 10−5) of all stars (ever formed) in the Universe, a much higher fraction (~ 10−3 -0.1) of massive compact object mergers can originate from the first stars, which carry valuable information of the early Universe. Finally, we explore the effects of primordial black holes, which can make up all or part of dark matter, on first star formation, and discuss their implications on using gravitational waves as a direct probe of dark matter

Available in PDF, EPUB and Kindle. Book excerpt: The concepts of dark matter and the cosmic web are some of the most significant developments in cosmology in the past century. They have decisively changed the classical cosmological paradigm, which was first elaborated upon during the first half of the 20th century but ran into serious problems in the second half. Today, they are integral parts of modern cosmology, which explains everything from the Big Bang to inflation to the large scale structure of the Universe.Dark Matter and Cosmic Web Story describes the contributions that led to a paradigm shift from the Eastern point of view. It describes the problems with the classical view, the attempts to solve them, the difficulties encountered by those solutions, and the conferences where the merits of the new concepts were debated. Amidst the science, the story of scientific work in a small country occupied by the Soviet Union and the tumultuous events that led to its breakup are detailed as well.This book is accompanied by a website which contains additional material: copies of the originals of some crucial papers, astronomical movies, and movies which showcase the private life of the author.

This book was released on 2024-01-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The observational evidence supporting the Big Bang (BB) is solid, making it widely believed the universe began as a nugget of energy that expanded. But that observational evidence addresses conditions occurring 380,000 years after the BB. The first 380,000 years of cosmic evolution is conjecture. The current theory centers around the Standard Model's vision of fields, forces, and particles inexplicably popping into existence within the first second. That conjecture has worked for many years and has inspired an edifice of theoretical support, but it stretches credulity and leaves too many unanswered questions. What if the nugget of energy did not instantaneously turn into particles but was left to expand and lose density? As it thinned, isolated density fluctuations would swirl and grow by accretion, eventually creating thick-density supermassive blackholes, light-density elementary particles, and a thin-density medium of dark energy. The support for this seemingly wild hypothesis is in the observational evidence demonstrating that everything we know of in the universe, including fields, forces, matter, and time, naturally evolves from relationships between those three energy densities. This is the story of those relationships. That profound realization comes through in the Second Edition of A New Vision of the Early Universe. It's the culmination of forty years of research and study by the author, Robert J. Conover. The depth of his research, attention to detail, clear prose, and philosophical approach to analyzing difficult issues conspire to make this a well-respected treatise. The work is supported by numerous citations, quotes, and observations from many leading physicists, cosmologists, and mathematicians. The treatise also addresses other issues in cosmology, such as the mystery of the missing anti-matter, the origin of particle mass, gravity, time dilation, and wave-particle duality. Sound reasoning and observational evidence makes this new vision one that invites confirmation or rejection on multiple levels. It will surely stimulate discussion, theoretical assault, and experimental analysis for years to come. It is a momentous journey through 380,000 years of evolution that has never before been so thoroughly analyzed or so vividly recounted.

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.

Available in PDF, EPUB and Kindle. Book excerpt: It is generally believed that most of the matter in the universe is dark, i.e. cannot be detected from the light which it emits (or fails to emit). Its presence is inferred indirectly from the motions of astronomical objects, specifically stellar, galactic, and galaxy cluster/supercluster observations. It is also required in order to enable gravity to amplify the small fluctuations in the cosmic microwave background enough to form the large-scale structures that we see in the universe today. For each of the stellar, galactic, and galaxy cluster/supercluster observations the basic principle is that if we measure velocities in some region, then there has to be enough mass there for gravity to stop all the objects flying apart. Dark matter has important consequences for the evolution of the Universe and the structure within it. According to general relativity, the Universe must conform to one of three possible types: open, flat, or closed. The total amount of mass and energy in the universe determines which of the three possibilities applies to the Universe. In the case of an open Universe, the total mass and energy density (denoted by the Greek letter Omega) is less than unity. If the Universe is closed, Omega is greater than unity. For the case where Omega is exactly equal to one the Universe is "flat". This book details leading-edge research from around the globe.

This book was released on 2013 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current major problems in particle physics and astrophysics are the source of possible new features: of The Standard Model, of the nature of Dark Matter, of the nature of Dark Energy, and of the nature of the Big Bang. In this book we propose an extended version of The Standard Model based on earlier work that adds another SU(2)X U(1) symmetry to the usual Standard Model, and an accompanying set of particles that we propose are the constituents of Dark Matter. This additional symmetry follows directly from a geometrical foundation for space-time within a 16 dimensional flat space that we call the Flatverse. Upon introducing a form of quantum coordinates we find that The Standard Model in those coordinates has no infinities, that the Big Bang is finite (no singularity), and that the Dark Energy that fuels the expansion of the universe has inflatons that consist of the imaginary part of the quantum coordinates - a free abelian gauge field. This field first stabilizes the universe in the Big Bang period and then causes a massive inflationary expansion. The complete theory has a remarkable convergence of features that remove infinities, identify the nature of Dark Matter and of Dark Energy, specify a physically acceptable Big Bang, and predict the observed expansion of the universe. In addition we address the recently reported discovery of the Higgs particle that "explains" the origin of the masses of the other elementary particles but does not explain the origin of the Higgs particle mass terms and thus leaves open the ultimate question - What is the origin of mass and inertia? We show that the only final answer can be that it arises as a separation constant in Higgs dynamic equations that include coordinates of this universe and a sister universe. These two 8-dimensional universes are embedded in the 16-dimensional Flatverse. Thus the sister universe is the ultimate source of mass and inertia for our universe. The Flatverse is an absolute reference frame that is consistent with Einstein's General Relativity according to General Relativists. The Flatverse very nicely provides an environment for the two universes - joining them together to provide mass and inertia at their most fundamental level as well as providing, at last, a concrete definition of inertial reference frames. Result: a fundamental synergy between mass, inertia, and inertial frames. In recent weeks major experimental findings on Dark Matter have been presented that at last begin to clarify the nature of Dark Matter and its interactions with "normal" matter. These findings are consistent with a Dark Matter SU(2) X U(1) set of interactions that parallels, to a great extent, the known ElectroWeak interactions of normal matter. We will explore a detailed theory of Dark Matter interactions, and their relation to ElectroWeak interactions in this book. It is based on our previous work. In the previous work we did not specify a relation between ElectroWeak and "DarkWeak" interactions due to the absence of experimental data. With the information now in hand we can develop a detailed relationship. Lastly, the book emphasizes again our belief that the origin of particle physics lies in a combination of Asynchronous Logic and space-time geometry."
