Available in PDF, EPUB and Kindle. Book excerpt: Unveiling the nature of dark matter is one of the greatest challenges of modern physics, at the interface between astrophysics, cosmology and particle physics. In this thesis, I tackle various aspects of indirect searches for dark matter particles, which provide a complementary approach to direct detection or collider experiments. We are now entering into an era of instruments with outstanding capabilities, so it was timely to tackle the problem of the dark matter density profile at the centers of galaxies with novel methods, which motivated this thesis. Taking advantage of these technological advances, I investigate new ways of probing the very central part of dark matter halos, especially focusing on dark matter spikes, i.e. very strong enhancements of the dark matter density that can form around supermassive black holes. I show that we can go beyond standard dark matter searches by studying photon emission from electrons and positrons produced in dark matter annihilation processes. In this context, I describe a new cosmic-ray propagation technique to account for injection by spiky distributions at the centers of galaxies. I develop novel models of the diffuse emission in the central regions of galaxies, focusing not only on the center of the Milky Way, but on the central regions of other galaxies as well. This allows me to explain recently reported observations and make predictions for future observations.

This book was released on 2006-02-23 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: TheFifthHEIDELBERGInternationalConferenceonDarkMatterinAst- and Particle Physics, DARK 2004, took place at Texas A&M University, College Station Texas, USA, October 3–9, 2004. It was, after Cape Town 2002, the second conference of this series held outside Germany. The earlier meetings, starting in 1996, were held in Heidelberg. Dark Matter is still one of the most exciting and central ?elds of ast- physics, particle physics and cosmology. The conference covered, as usual for this series, a large range of topics, theoretical and experimental. Theoretical talks covered SUSY/SUGRA phenomenology, which provides at present a preferred theoretical framework for the existence of cold dark matter. Also included were other possible explanations of dark matter such as SUSY Q balls, exciting New Symmetries, etc. The most important experiments in the underground search for cold and hot dark matter were presented. Talks describing the current experimental dark matter bounds, what might be obtained in the near future, and the reach of future large (i.e. one ton) detectors were given. The potential of future colliders to correlate accelerator physics with dark matter searches was also outlined. Thus the reader will be able to see the present status and future prospects in the search for dark matter. The exciting astronomical evidence for dark matter and corresponding observations concerning the Milky Way’s black hole, high-redshift clusters, wakes in dark matter halos were other important topics at the conference.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper we discuss two mechanisms by which high energy electrons resulting from dark matter annihilations in or near the Sun can arrive at the Earth. Specifically, electrons can escape the sun if DM annihilates into long-lived states, or if dark matter scatters inelastically, which would leave a halo of dark matter outside of the sun. Such a localized source of electrons may affect the spectra observed by experiments with narrower fields of view oriented towards the sun, such as ATIC, differently from those with larger fields of view such as Fermi. We suggest a simple test of these possibilities with existing Fermi data that is more sensitive than limits from final state radiation. If observed, such a signal will constitute an unequivocal signature of dark matter.

Available in PDF, EPUB and Kindle. Book excerpt: Through use of a lecture-slide format, this book presents an astrophysics detective story that chronicles Jerome Drexler's literature search for astronomical clues and evidence to unveil the nature of dark matter. There are a number of mysteries in astrophysics and cosmology that have remained unsolved for decades. What is dark matter? How exactly are stars created? In 1998, it was determined from supernova studies that the expansion of the Universe was accelerating, thereby creating the mystery of dark energy. Astrophysicists have developed mutually exclusive, single-phenomenon theories for each of these three phenomena, but not a unified theory for all three of them. The author's original goal was to identify dark matter, a decades-old mystery. In the process, he developed a new theory for dark matter and illuminated the nature of dark energy and the process of Sun formation. Since dark matter may have been instrumental in the creation of galaxies and stars, the author decided to test his new dark matter theory on the formation of the Sun. The results were very encouraging. He next sought a possible link between dark matter and the accelerating expansion of the Universe, which is attributed to the mysterious dark energy. Using his dark matter theory and the laws of physics, the author explained the accelerating expansion of the Universe in a plausible manner. This book chronicles the author's search for a unified astrophysical theory and how it finally evolved.

Download or read book Large Hadron Collider Phenomenology written by M. Kramer and published by CRC Press. This book was released on 2004-09-30 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the Large Hadron Collider (LHC) under construction and due to come online in 2007, it is appropriate to engage in a focused review on LHC phenomenology. At a time when most of the experimental effort is centered on detector construction and software development, it is vitally important to direct the experimental community and, in particular, new researchers on the physics phenomena expected from the LHC. Large Hadron Collider Phenomenology covers the capabilities of LHC, from searches for the Higgs boson and physics beyond the standard model to detailed studies of quantum chromodynamics, the B-physics sectors, and the properties of hadronic matter at high energy density as realized in heavy-ion collisions. Written by experienced researchers and experimentalists, this reference examines the basic properties and potentials of the machine, detectors, and software required for physics analyses. The book starts with a basic introduction to the standard model and its applications to the phenomena observed at high energy collisions. Later chapters describe the key technological challenges facing the construction of the LHC machine, the operating detectors of the LHC, and the vast computing grid needed to analyze the data. In the final sections, the contributors discuss the quark-gluon plasma (QGP), explore questions and predictions for the LHC program, and examine the physics opportunities of the LHC using information from the forward region. By surveying the difficult challenges of the LHC development while also assessing the novel processes that the LHC will perform, Large Hadron Collider Phenomenology aids less seasoned physicists as well as existing researchers in discovering the numerous possibilities of the LHC.

Download or read book Electroweak-Interacting Spin-1 Dark Matter and Its Phenomenology written by Motoko Fujiwara and published by Springer Nature. This book was released on 2023-05-05 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers construction of a renormalizable effective theory of electroweak-interacting spin-1 dark matter (DM). The effective theory realizes minimal but essential features of DM predicted in extra-dimension models, and enables to systematically treat non-perturbative corrections such as the Sommerfeld effects. Deriving an annihilation cross section including the Sommerfeld effects based on the effective theory, the author discusses the future sensitivity of observations to gamma-ray from the Galactic Center. As a result, the author explains the monochromatic gamma-ray signatures originate from two photons (γγ) or photon and Z boson (γZ) produced in the process of DM annihilations, and concludes a possible scenario that unstable neutral spin-1 particles (Z’) appear and results in a spectral peak in addition to the one caused by γγ and γZ channels in gamma-ray observations. If those two spectral peaks are observed, the masses of spin-1 DM and Z’ would be reconstructed.

Available in PDF, EPUB and Kindle. Book excerpt: For over ten years, the dark side of the universe has been headline news. Detailed studies of the rotation of spiral galaxies, and 'mirages' created by clusters of galaxies bending the light from very remote objects, have convinced astronomers of the presence of large quantities of dark (unseen) matter in the cosmos. The most striking fact is that they seem to compromise about 95% of the matter/energy content of the universe. As for ordinary matter, although we are immersed in a sea of dark particles, including primordial neutrinos and photons from fossil cosmological radiation, both we and our environment are made of ordinary, 'baryonic' matter. Authors Mazure and Le Brun present the inventory of matter, baryonic and exotic, and investigating the nature and fate of matter's twin, anti-matter. They show how technological progress has been a result of basic research, in tandem with the evolution of new ideas, and how the combined effect of these advances might help lift the cosmic veil.

Download or read book Complementarity in Dark Matter Phenomenology written by Alexander Matthew Wijangco and published by . This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The particle nature of dark matter remains an open question to the physics community, despite a monumental effort to determine its properties. These efforts have resulted in a wealth of experimental knowledge and a rich model space of possible explanations. Dark matter phenomenology stands at the intersection of these efforts, and this thesis contains a series of works that attempt to constrain or construct models based on the empirical data. The first of these works details the insights the initial results of the LHC had on isospin violating dark matter in the context of effective operators. The next work deals with the possible effective operators between Dirac dark matter and photon lines at indirect detection experiments. The third is about a model of light scalar mediators used to explain a possible signal at the CDMS experiment. The fourth and final work concerns itself with a particular annihilation topology generated by dark matter going to on-shell mediators.

Download or read book The Physics of the Dark Photon written by Marco Fabbrichesi and published by Springer Nature. This book was released on 2020-11-23 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the dark photon which is a new gauge boson whose existence has been conjectured. Due to its interaction with the ordinary, visible photon, such a particle can be experimentally detected via specific signatures. In this book, the authors review the physics of the dark photon from the theoretical and experimental point of view. They discuss the difference between the massive and the massless case, highlighting how the two phenomena arise from the same vector portal between the dark and the visible sector. A review of the cosmological and astrophysical observations is provided, together with the connection to dark matter physics. Then, a perspective on current and future experimental limits on the parameters of the massless and massive dark photon is given, as well as the related bounds on milli-charged fermions. The book is intended for graduate students and young researchers who are embarking on dark photon research, and offers them a clear and up-to-date introduction to the subject.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes these issues in terms of links, between cosmology, particle and nuclear physics, as well as between cosmology, atmospheric and terrestrial physics. It studies the constituents of dark matter (classified as hot warm and cold) first in terms of their individual structures, and second, in terms of facilities available to detect these structures. Neutrinos are treated as a separate entity. The last chapter details the real-time stories about the "regions" that were not explored thus far, for lack of advanced technology. Their untold stories (which span up to 2010) are illustrated here datewise in full. The book concludes with the latest news that the Large Hadron Collider team at CERN has finally succeeded in producing 7 trillion electronic Volts of energy by creating head-on-collisions of protons and more protons (in search of God-particle).

Download or read book Dark Matter in Astrophysics and Particle Physics written by Hans Volker Klapdor-Kleingrothaus and published by World Scientific. This book was released on 2010 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark matter and dark energy are one of the central mysteries in modern physics, although modern astrophysical and cosmological observations and particle physics experiments can and will provide vital clues in uncovering its true nature. The DARK 2009 Conference brought together World?s leading researchers in both astrophysics and particle physics, providing an opportunity and platform to present their latest results to the community. The topics covered are wide-ranging, from terrestrial underground experiments to space experimental efforts to search for dark matter, and on the theoretical aspects, from the generating of a fifth family as origin of dark matter, extra dimensions and dark matter to non-standard Wigner classes and dark matter. One of the new highlights was certainly a possible connection between a neutrino mass as observed by nuclear double beta decay and the dark energy. Highly important and relevant in its field, the book presents a vital snapshot of the sometimes seemingly disparate areas of dark matter research and offers an exciting overview of current ideas and future directions.
