Symposia Day (PPD - PPD) - Dark Matter and Neutrinos / Matière noire et neutrinos

Invited Speaker / Conférencier(ère) invité(e)

Low mass accelerated dark matter (DM) is very well motivated and has been a subject of much attention in the literature. These fast-moving particles can gain enough kinetic energy to surpass the energy thresholds of some Large volume terrestrial detectors. For instance, fast-moving DM can deposit sizable amounts of energy at both large volume neutrino detectors and dark matter direct detection...

Symposia Day (PPD - PPD) - Dark Matter and Neutrinos / Matière noire et neutrinos

Invited Speaker / Conférencier(ère) invité(e)

The Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB is a world-leading direct detection experiment currently under construction, expected to begin full science runs next year. The successor to the SuperCDMS detectors previously operated at the Soudan Underground Laboratory in Minnesota, it will continue the progression of ever-improving dark matter sensitivities using cryogenic Ge and Si...

4577. Dark Matter at Finite Temperature: Oscillations, Resonances and Scattering

Oral (Non-Student) / Orale (non-étudiant(e))

The microphysical properties of Dark Matter (DM), such as its mass and coupling strength, are typically assumed to retain their vacuum values for any given model when considering DM behaviour at a range of scales. However, DM interactions in different astrophysical and cosmological environments is impacted by the properties of the background which in turn can substantially affect both DM...

4487. Limits on Non-Relativistic Matter During Big-Bang Nucleosynthesis

Symposia Day (PPD - PPD) - Dark Matter and Neutrinos / Matière noire et neutrinos

Oral (Non-Student) / Orale (non-étudiant(e))

Big-bang nucleosynthesis (BBN) probes the cosmic mass-energy density at temperatures $\sim 10$ MeV to $\sim 100$ keV. Here, we consider the effect of a cosmic matter-like species that is non-relativistic and pressureless during BBN. Such a component must decay; doing so during BBN can alter the baryon-to-photon ratio, $\eta$, and the effective number of neutrino species. We use light...
