Phenomenology of Dark Matter via a Bimetric Extension of General Relativity [PDF]
, 2015 We propose a relativistic model of dark matter reproducing at once the concordance cosmological model $\Lambda$-Cold-Dark-Matter ($\Lambda$-CDM) at cosmological scales, and the phenomenology of the modified Newtonian dynamics (MOND) at galactic scales ...

DUNE Prospect for Leptophobic Dark Matter
Advances in High Energy Physics, 2020 Highly energetic proton/electron beam fixed-target experiments extend an opportunity to probe the sub-GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub-GeV ...

Assessment of Dark Matter Models Using Dark Matter Correlations across Dwarf Spheroidal Galaxies
Universe, 2022 The predicted size of dark matter substructures in kilo-parsec scales is model-dependent. Therefore, if the correlations between dark matter mass densities as a function of the distances between them are measured via observations, we can scrutinize dark ...

Hierarchy in the Phase Space and Dark Matter Astronomy [PDF]
, 2009 We develop a theoretical framework for describing the hierarchical structure of the phase space of cold dark matter haloes, due to gravitationally bound substructures.

Constraints on anharmonic corrections of fuzzy dark matter
Journal of High Energy Physics, 2018 The cold dark matter (CDM) scenario has proved successful in cosmology. However, we lack a fundamental understanding of its microscopic nature. Moreover, the apparent disagreement between CDM predictions and subgalactic-structure observations has ...

To Observe, or Not to Observe, Quantum-Coherent Dark Matter in the Milky Way, That is a Question
Frontiers in Astronomy and Space Sciences, 2021 In recent years, Bose-Einstein-condensed dark matter (BEC-DM) has become a popular alternative to standard, collisionless cold dark matter (CDM). This BEC-DM -also called scalar field dark matter (SFDM)- can suppress structure formation and thereby ...

Holographic interacting dark energy in the braneworld cosmology
, 2007 We investigate a model of brane cosmology to find a unified description of the radiation-matter-dark energy universe. It is of the interacting holographic dark energy with a bulk-holographic matter $\chi$.

Axino cold dark matter revisited [PDF]
Journal of High Energy Physics, 2012 Abstract Axino arises in supersymmetric versions of axion models and is a natural candidate for cold or warm dark matter. Here we revisit axino dark matter produced thermally and non-thermally in light of recent developments. First we discuss the definition of axino relative to low energy axion one for several KSVZ and DFSZ models ...

Particle Physics Approach to Dark Matter
, 2006 We review the main proposals of particle physics for the composition of the cold dark matter in the universe. Strong axion contribution to cold dark matter is not favored if the Peccei-Quinn field emerges with non-zero value at the end of inflation and ...
