It is now widely accepted that most of mass-energy in the universe is unobserved except by its gravitational effects. Baryons make only about 4% of the total, with ''dark matter'' making up about 23% and the ''dark energy'' responsible for the accelerated expansion of the universe making up the remainder. We focus on the dark matter, which is the primary constituent of galaxies. We outline the observed properties of this material, enumerating some candidates covering 90 orders of magnitude in…

Dark Matter in Modern Cosmology
The presence of Dark Matter is required in the Universe regulated by the standard general relativistic theory of gravitation. The nature of Dark Matter is however still elusive to any experimental
On the Nature of Dark Matter and Dark Energy
It is known that all candidates in dark matter (DM) particles (neutrinos, axions, supersymmetric particles etc.) can not explain the basic properties of DM. The same can be said on the proposed
Simulation Studies on the Search for Dark Matter in Dwarf Spheroidal Galaxies with H
The H.E.S.S. Project, (High Energy Stereoscopic System), is an array of four imaging Cherenkov Telescopes located at the southern hemisphere in the Khomas Highland in Namibia. High energetic
TeV γ-rays and the largest masses and annihilation cross sections of neutralino dark matter
Motivated by the interpretation of the recent results on the TeV gamma radiation from the galactic center, including the new 2004 HESS data, as a by-product of dark matter particles annihilations, we
Multi-frequency analysis of neutralino dark matter annihilations in the Coma cluster
We study the astrophysical implications of neutralino dark matter annihilations in galaxy clusters, with a specific application to the Coma cluster. We first address the determination of the dark
Increasing the neutralino relic abundance with slepton coannihilations: consequences for indirect dark matter detection
We point out that if the lightest supersymmetric particle (LSP) is a higgsino- or wino-like neutralino, the net effect of coannihilations with sleptons is to increase the relic abundance, rather than
Tracking quintessence and cold dark matter candidates
We study the generation of a kination-dominated phase in the context of a quintessential model with an inverse-power-law potential and a Hubble-induced mass term for the quintessence field. The
Quintessential kination and thermal production of gravitinos and axinos
The impact of a kination-dominated phase generated by a quintessential exponen-tial model on the thermal abundance of gravitinos and axinos is investigated. We find that their abundances become
Current status of different detector technology in the searches of dark matter events
In this article, we review the possible candidates of dark matter and their proposed properties. We have focused on different methods used for the detection of the dark matter candidates such as,
Nature's Greatest Puzzles
It is a pleasure to be part of the SLAC Summer Institute again, not simply because it is one of the great traditions in our field, but because this is a moment of great promise for particle physics.


PeV-scale supersymmetry
Although supersymmetry has not been seen directly by experiment, there are powerful physics reasons to suspect that it should be an ingredient of nature and that superpartner masses should be
The early Universe
In the past few years one of the most exciting areas of research in physics has been the interdisciplinary field of cosmology and particle physics. The NSF's Institute for Theoretical Physics in
Supersymmetric unification without low energy supersymmetry and signatures for fine-tuning at the LHC
The cosmological constant problem is a failure of naturalness and suggests that a fine-tuning mechanism is at work, which may also address the hierarchy problem. An example — supported by Weinberg's
Implications of Supersymmetry Breaking with a Little Hierarchy between Gauginos and Scalars
From a theoretical point of view it is not hard to imagine gaugino masses being much lighter than scalar masses. The dominant contributions to gaugino masses are then their anomaly-mediated values.
Aspects of Split Supersymmetry
We explore some fundamental differences in the phenomenology, cosmology and model building of Split Supersymmetry compared with traditional low-scale supersymmetry. We show how the mass spectrum of
Early SPI/INTEGRAL constraints on the morphology of the 511 keV line emission in the 4th galactic quadrant
We provide first constraints on the morphology of the 511 keV line emission from the galactic centre region on basis of data taken with the spectrometer SPI on the INTEGRAL gamma-ray observatory. The
