Particle dark matter: Evidence, candidates and constraints
TLDR
The current status of particle dark matter, including experimental evidence and theoretical motivations, including direct and indirect detection techniques, is discussed in this paper. But the authors focus on neutralinos in models of supersymmetry and Kaluza-Klein dark matter in universal extra dimensions.About:

Solar Constraints on Asymmetric Dark Matter
TL;DR: In this article, the authors investigated the impact of a type of dark matter on the evolution of the Sun, namely, the flux of solar neutrinos and helioseismology, and found that dark matter particles with a mass smaller than 15 GeV, a spin-independent scattering cross section on baryons of the order of a picobarn, and an η-asymmetry with a value in the interval 10−12-10−10-10 −10, would induce a change in the Sun flux.
Journal ArticleDOI
Dark Matter and Synchrotron Emission from Galactic Center Radio Filaments
TL;DR: In this paper, it was shown that the electrons and positrons created through the annihilations of a relatively light (~5-10 GeV) dark matter particle with the cross section predicted for a simple thermal relic can provide a compelling match to the intensity, spectral shape, and flux variation of the NRFs.

Sensitivity of CTA to dark matter signals from the Galactic Center
TL;DR: In this paper, the authors investigate the sensitivity of the upcoming Cherenkov Telescope Array (CTA) to dark matter annihilation and decay in the Galactic Center and find that the sensitivity achieved by CTA to annihilation signals is strongly dependent on the inner profile slope, whereas the dependence is more mild in the case of dark matter decay.

TL;DR: In this article, it was shown that a global network of atomic magnetometers is sufficiently sensitive to pseudoscalar couplings to atomic spins so that a transit through an axion star or $Q$-ball could be detected over a broad range of unexplored parameter space.
Journal ArticleDOI
Dark matter subhaloes as gamma-ray sources and candidates in the first Fermi-LAT catalogue
TL;DR: Based on realistic subhalo models and current observational constraints on annihilating dark matter scenarios, Wang et al. as discussed by the authors predicted that one massive Galactic sub-halo between 10 6 and 10 8 M may already be present in the 11-month catalogue of Fermi-LAT.

TL;DR: In this article, the authors find that the emerging standard model of cosmology, a flat -dominated universe seeded by a nearly scale-invariant adiabatic Gaussian fluctuations, fits the WMAP data.

Large Mass Hierarchy from a Small Extra Dimension
TL;DR: In this paper, the weak scale is generated from the Planck scale through an exponential hierarchy, but this exponential arises not from gauge interactions but from the background metric, which is a slice of spacetime.
Journal ArticleDOI
The Structure of cold dark matter halos
TL;DR: In this article, high-resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple universal profile.

TL;DR: In this article, the Robertson-Walker Metric is used to measure the radius of the Planck Epoch in the expanding universe, which is a measure of the number of atoms in the universe.
Journal ArticleDOI
The Hierarchy problem and new dimensions at a millimeter
TL;DR: In this paper, the authors propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor, and they take as the only fundamental short distance scale in nature.
