El problema de la existencia de la materia oscura (DM) es una cuesti on de gran importancia para la f sica del siglo XXI. El Modelo Cosmol ogico Est andar proporciona una buena descripci on de la evoluci on del Universo, de acuerdo con los datos de experimentos como COBE, WMAP y PLANCK. Seg un este modelo, el 69:2% del contenido de energ a del Universo est a constituido por un tipo de energ a oscura con presi on, responsable de la expansi on acelerada, el 26:8% por DM, mientras que la componente conocida de la materia ser a s olo alrededor del 5% del total. Sin embargo, la componente oscura de la materia se ha detectado hasta ahora s olo por medio de pruebas gravitacionales. En el caso de que dicha componente est e constituida por part culas, distintos experimentos de b usqueda directa e indirecta en tierra y en sat elites, podr an detectar esta nueva part cula por medio de su interacci on con la materia ordinaria y tambi en a trav es de los productos secundarios de su aniquilaci on y desintegraci on en fuentes astrof sicas. Desde un punto de vista m as te orico, la b usqueda de DM incluye modelos m as all a del Modelo Est andar (SM) de part culas elementales, modelos de supersimetr a y dimensiones extra. Una introducci on m as detallada a la cosmolog a y al problema de la DM se presenta en el Cap tulo 1, mientras que en el Cap tulo 2 introducimos la b usqueda de DM en colisionadores de part culas y en experimentos de b usqueda directa e indirecta.

Dark matter is among the most important open problems in modern physics. Aimed at graduate students and researchers, this book describes the theoretical and experimental aspects of the dark matter problem in particle physics, astrophysics and cosmology. Featuring contributions from 48 leading theorists and experimentalists, it presents many aspects, from astrophysical observations to particle physics candidates, and from the prospects for detection at colliders to direct and indirect searches. The book introduces observational evidence for dark matter along with a detailed discussion of the state-of-the-art of numerical simulations and alternative explanations in terms of modified gravity. It then moves on to the candidates arising from theories beyond the Standard Model of particle physics, and to the prospects for detection at accelerators. It concludes by looking at direct and indirect dark matter searches, and the prospects for detecting the particle nature of dark matter with astrophysical experiments.

This thesis presents the results of indirect dark matter searches in the gamma-ray sky of the near Universe, as seen by the MAGIC Telescopes. The author has proposed and led the 160 hours long observations of the dwarf spheroidal galaxy Segue 1, which is the deepest survey of any such object by any Cherenkov telescope so far. Furthermore, she developed and completely characterized a new method, dubbed “Full Likelihood”, that optimizes the sensitivity of Cherenkov instruments for detection of gamma-ray signals of dark matter origin. Compared to the standard analysis techniques, this novel approach introduces a sensitivity improvement of a factor of two (i.e. it requires 4 times less observation time to achieve the same result). In addition, it allows a straightforward merger of results from different targets and/or detectors. By selecting the optimal observational target and combining its very deep exposure with the Full Likelihood analysis of the acquired data, the author has improved the existing MAGIC bounds to the dark matter properties by more than one order of magnitude. Furthermore, for particles more massive than a few hundred GeV, those are the strongest constraints from dwarf galaxies achieved by any gamma-ray instrument, both ground-based or space-borne alike.

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.

This thesis describes the search for Dark Matter at the LHC in the mono-jet plus missing transverse momentum final state, using the full dataset recorded in 2012 by the ATLAS Experiment. It is the first time that the number of jets is not explicitly restricted to one or two, thus increasing the sensitivity to new signals. Instead, a balance between the most energetic jet and the missing transverse momentum is required, thus selecting mono-jet-like final states. Collider searches for Dark Matter have typically used signal models employing effective field theories (EFTs), even when comparing to results from direct and indirect detection experiments, where the difference in energy scale renders many such comparisons invalid. The thesis features the first robust and comprehensive treatment of the validity of EFTs in collider searches, and provides a means by which the different classifications of Dark Matter experiments can be compared on a sound and fair basis.

Dark Matter is one of the pillars of Modern Cosmology, but its nature remains unknown. I will first review the current status of particle Dark Matter, including experimental evidence and theoretical motivations. I will then focus on recent developments in indirect searches, in light of recent observational results from the space-based gamma-ray observatory INTEGRAL (energy scale ≈ MeV), and from ground-based Air Cherenkov Telescopes such as HESS (energy scale ≈ TeV). Finally I discuss the prospects of indirect detection with GLAST, scheduled to be launched in 2007.
