The moment of truth for WIMP Dark Matter [PDF]

open access: yesNature, 2010
We know that dark matter constitutes 85% of all the matter in the Universe, but we do not know of what it is made. Amongst the many Dark Matter candidates proposed, WIMPs (weakly interacting massive particles) occupy a special place, as they arise ...

Earth-mass dark-matter haloes as the first structures in the early Universe

open access: yesNature, 2005
The Universe was nearly smooth and homogeneous before a redshift of z = 100, about 20 million years after the Big Bang. After this epoch, the tiny fluctuations imprinted upon the matter distribution during the initial expansion began to collapse because ...

Search for Milli-Charged particles from the Sun at IceCube

open access: yesJournal of High Energy Physics, 2022
It is assumed that heavy dark matter particles ϕ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector.

Strategies for Determining the Nature of Dark Matter [PDF]

open access: yes, 2008
In this review, we discuss the role of the various experimental programs taking part in the broader effort to identify the particle nature of dark matter.

Minimal consistent Dark Matter models for systematic experimental characterisation: fermion Dark Matter

open access: yesJournal of High Energy Physics, 2022
The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and model-independent tool for comparing the bounds and reach of

Asymmetries in extended dark sectors: a cogenesis scenario

open access: yesJournal of High Energy Physics, 2023
The observed dark matter relic abundance may be explained by different mechanisms, such as thermal freeze-out/freeze-in, with one or more symmetric/asymmetric components. In this work we investigate the role played by asymmetries in determining the yield

The Z 7 model of three-component scalar dark matter

open access: yesJournal of High Energy Physics, 2023
We investigate, for the first time, a scenario where the dark matter consists of three complex scalar fields that are stabilized by a single Z 7 symmetry.

The continuum dark matter zoo

open access: yesJournal of High Energy Physics, 2023
We generalize the recently proposed continuum dark matter model to the case where the dark matter consists of a spin-1/2 or spin-1 gapped continuum. We construct simple continuum analogs of weakly interacting massive particles annihilating through the Z ...

Unraveling the Scotogenic model at muon collider

open access: yesJournal of High Energy Physics, 2022
The Scotogenic model extends the standard model with three singlet fermion N i and one inert doublet scalar η to address the common origin of tiny neutrino mass and dark matter. For fermion dark matter N 1, a hierarchical Yukawa structure ∣ y 1 e ∣ ≪ ∣ y

Ultra-Light Dark Matter in Ultra-Faint Dwarf Galaxies [PDF]

open access: yes, 2016
Cold Dark Matter (CDM) models struggle to match the observations at galactic scales. The tension can be reduced either by dramatic baryonic feedback effects or by modifying the particle physics of CDM.
