Limits on spin-dependent WIMP-proton cross-sections using the DRIFT-IId directional dark matter detector [PDF]
, 2011 The nature of dark matter remains one of the biggest questions in physics today. Weakly Interacting Massive Particles (WIMPs) are a particularly well motivated candidate for the missing matter that makes up 85% of the mass of the Universe.

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

Cold Particle Dark Matter [PDF]
, 2021 Possible dark matter candidates in particle physics span a mass range extending over fifty orders of magnitude. In this review, we consider the range of masses from a few keV to a few hundred TeV, which is relevant for cold particle dark matter.

Two natural scenarios for dark matter particles coexisting with supersymmetry [PDF]
Modern Physics Letters A, 2019 We describe two natural scenarios in which both dark matter, weakly interacting massive particles (WIMPs) and a variety of supersymmetric partners should be discovered in the foreseeable future. In the first scenario, the WIMPs are neutralinos, but they are only one component of the dark matter, which is dominantly composed of other relic particles ...

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

Natural Dark Matter from an unnatural Higgs boson and new colored particles at the TeV scale [PDF]
Journal of High Energy Physics, 2007 The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not ensure the presence of new particles charged under SU(3)_C, resulting in challenging LHC phenomenology.

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

A Dark-Matter Search Using the Final CDMS II Dataset and a Novel Detector of Surface Radiocontamination [PDF]
, 2012 Substantial evidence from galaxies, galaxy clusters, and cosmological scales suggests that ~85% of the matter of our universe is invisible. The missing matter, or "dark matter" is likely composed of non-relativistic, non-baryonic particles, which have ...
