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:

Constraining Minimal $U(1)_{B-L}$ model from Dark Matter Observations
Tanushree Basak,Tanmoy Mondal +1 more
TL;DR: In this paper, the authors studied the B-L$ gauge extension of the Standard Model which contains a singlet scalar and three right-handed neutrinos and showed that the vacuum expectation value of the single scalar breaks the $U(1)_{B-L}$ symmetry.
Journal ArticleDOI
Constraining Non-thermal and Thermal properties of Dark Matter
TL;DR: In this paper, the authors describe the evolution of dark matter abundance from the very onset of its creation from inflaton decay under the assumption of an instantaneous reheating, and identify the thermal freeze-out, freeze-in and non-thermal regions of the allowed parameter space.

A RIAF Interpretation for the Past Higher Activity of the Galactic Center Black Hole and the 511 keV Annihilation Emission
TL;DR: In this article, it is shown that this increased rate and its duration are theoretically reasonable in the Galactic center environment, while the accretion rate suddenly dropped about 300yr ago, most likely because of the shell passage of the supernova remnant Sgr A East.
Journal ArticleDOI
Cold dark matter with MOND scaling
TL;DR: In this paper, a duality between cold dark matter and modified Newtonian dynamics (MOND) was proposed, based on the recent entropic reinterpretation of Newton's laws of motion.
Journal ArticleDOI
e+ and bar p from inert doublet model dark matter
TL;DR: In this paper, the authors consider three benchmark candidates, all consistent with the WMAP cosmic abundance and existing direct detection experiments, and confront the predictions of the model with the recent PAMELA, ATIC and HESS data, and argue that the positron and anti-proton fluxes may be large, but still consistent with expected background, unless there is an enhancement (boost factor) in the local density of dark matter.

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.

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.

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.
