Novel constraints on the particle nature of dark matter from stellar streams [PDF]

open access: bronzeJournal of Cosmology and Astroparticle Physics, 2021
Tidal streams are highly sensitive to perturbations from passing dark matter (DM) subhalos and thus provide a means of measuring their abundance. In a recent paper, we analyzed the distribution of stars along the GD-1 stream with a combination of data from the Gaia satellite and the Pan-STARRS survey, and we demonstrated that the population of DM ...

Strong gravitational lensing probes of the particle nature of dark matter [PDF]

open access: green, 2009
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these candidates may have scattering (and other) cross section properties that are consistent with the dark matter abundance, BBN, and the most scales in the matter power spectrum ...

Faint and Extended Galaxies as Probes for Understanding the Nature of Dark Matter Particles [PDF]

open access: diamondInternational Journal of High Energy Physics
This study delves into the complex nature of dark matter, a fundamental yet poorly understood component of the universe that constitutes approximately 27% of its total mass-energy content. By focusing on faint and extended galaxies specifically dwarf galaxies and low surface brightness galaxies this research aims to elucidate the properties of dark ...

Prospects for determining the particle/antiparticle nature of WIMP dark matter with direct detection experiments [PDF]

open access: diamondJournal of High Energy Physics, 2017
Recientemente se señaló que las señales de detección directa de al menos tres objetivos diferentes se pueden utilizar para determinar si la partícula de materia oscura (DM) es diferente de su antipartícula. En este trabajo, examinamos en detalle la viabilidad de esta prueba en diferentes condiciones, motivados por propuestas para futuros detectores ...

Gamma-ray lines may reveal the CP nature of the dark matter particle [PDF]

open access: greenJournal of Cosmology and Astroparticle Physics, 2019
Determining the fundamental properties of the dark matter is one of the most important open problems in particle physics today. If the dark matter particle has spin zero, one of these properties is its CP nature. That is, whether it is CP-even (scalar), CP-odd (pseudoscalar), or if its interactions violate CP.

Associated production of neutrino and dark fermion at future lepton colliders

open access: yesJournal of High Energy Physics, 2023
Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector fermion at the future e + e − colliders such as CEPC, FCC-ee, ILC, and ...

Multi-component dark sectors: symmetries, asymmetries and conversions

open access: yesJournal of High Energy Physics, 2022
We study the relic abundance of several stable particles from a generic dark sector, including the possible presence of dark asymmetries. After discussing the different possibilities for stabilising multi-component dark matter, we analyse the final relic
