Medium and High Energy Seminar: Tien-Tien Yu (University of Oregon) "Astrophysical Uncertainties in Dark Matter-Electron Scattering and How to Elude Them"

Speaker Tien-Tien Yu (University of Oregon)
Date: 4/12/2021
Time: 1:30 p.m.
Location: Zoom
Event Contact: Marjorie Gamel
Sponsor: Department of Physics
Event Type: Seminar/Symposium
In this talk, I will discuss how dark matter-electron scattering calculations depend on the underlying astrophysical model of the dark matter halo velocity distribution. I will give a brief review of the main astrophysical halo models and the measurements of their associated parameters. The predictions for dark matter-electron scattering calculations are highly sensitive to the specific choice of halo model and parameters, which in turn affects our interpretation of experimental results. Finally, I will introduce work from an ongoing effort to interpret and present dark matter-electron scattering experimental results in a manner that is agnostic about the underlying astrophysical halo model.
This seminar is co-sponsored by ICASU.
