Available in PDF, EPUB and Kindle. Book excerpt: Astrophysical observations from galactic to cosmological scales point to a substantial non-baryonic component to the universe's total matter density. Although very little is presently known about the physical properties of dark matter, its existence offers some of the most compelling evidence for physics beyond the standard model (BSM). In the weakly interacting massive particle (WIMP) scenario, the dark matter consists of particles that possess weak-scale interactions with the particles of the standard model, offering a compelling theoretical framework that allows us to understand the relic abundance of dark matter as a natural consequence of the thermal history of the early universe. From the perspective of particle physics phenomenology, the WIMP scenario is appealing for two additional reasons. First, many theories of BSM physics contain attractive WIMP candidates. Second, the weak-scale interactions between WIMPs and standard model particles imply the possibility of detecting scatterings between relic WIMPs and detector nuclei in direct detection experiments, products of WIMP annihilations at locations throughout the galaxy in indirect detection programs, and WIMP production signals at high-energy particle colliders. In this work, we use an effective field theory approach to study model-independent dark matter phenomenology in direct detection and collider experiments. The maverick dark matter scenario is defined by an effective field theory in which the WIMP is the only new particle within the energy range accessible to the Large Hadron Collider (LHC). Although certain assumptions are necessary to keep the problem tractable, we describe our WIMP candidate generically by specifying only its spin and dominant interaction form with standard model particles. Constraints are placed on the masses and coupling constants of the maverick WIMPs using the Wilkinson Microwave Anisotropy Probe (WMAP) relic density measurement and direct detection exclusion data from both spin-independent (XENON100 and SuperCDMS) and spin-dependent (COUPP) experiments. We further study the distinguishability of maverick WIMP production signals at the Tevatron and the LHC--at its early and nominal configurations--using standard simulation packages, place constraints on maverick WIMP properties using existing collider data, and determine projected mass reaches in future data from both colliders. We find ourselves in a unique era of theoretically-motivated, high-precision dark matter searches that hold the potential to give us important insights, not only into the nature of dark matter, but also into the physics that lies beyond the standard model.

Available in PDF, EPUB and Kindle. Book excerpt: Several phenomenological aspects of dark matter detection are examined, involving both MACHO and WIMP dark matter candidates. Dark matter detection can be used to probe both particle physics models and the structure of the galaxy, providing answers to questions in both physics and astronomy.

Book excerpt: One of the most puzzling problems of modern physics is the identification of the nature a non-relativistic matter component present in the universe, contributing to more than 25% of the total energy budget, known as Dark Matter. Weakly Interacting Massive Particles (WIMPs) are among the best motivated dark matter candidates. However, in light of non conclusive detection signals and strong constraints from collider, direct and indirect detection experiments, this thesis presents constraints on several realizations of the WIMP paradigm in the context of simplified dark matter models. More elaborated models considering extended gauge structures are discussed further on, such as constructions involving generalized Chern-Simons couplings and a specific WIMP scenario motivated by some recently observed flavor anomalies related to the RK(*) observable. The second part of this thesis is devoted to the discussion of an alternative dark matter thermal production mechanism where an explicit realization of the Strongly Interacting Massive Particles (SIMPs) paradigm is discussed in the context of a non-Abelian hidden gauge structure. In a last part, the possibility of producing non-thermally a dark matter component via the "freeze-in" mechanism was investigated and the strong impact of the postinationary reaheating stage of the universe on such constructions illustrated by the specific case where dark matter density production is mediated by a heavy spin-2 field in addition to the standard graviton.

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: The modern roots on the dark matter problem were basically launched in the 30s, with Zwicky's observations on a notorious discrepancy of mass in coma cluster that presented 500 times the mass than expected using the Newtonian theory (Virial theorem). Curiously, almost 90 years have passed, and the dark matter problem persists and is one of the most common challenges in both observational and theoretical physics. The Dark Matter is a rapid communication on the status-quo of the dark matter phenomenology as well as a presentation of new discussions on the theme.
