Dark matter (DM) is roughly 80% of the matter in the universe and not made up of any known particle. It interacts with other particles weakly or not at all except by gravity. Direct detection experiments aim to observe low-energy recoils of nuclei induced by interactions with DM particles, especially for the most popular candidate weakly interacting massive particles (WIMPs) with mass from few GeV to 1 TeV. To expand a direct detector’s coverage of low-mass WIMPs, or more generically light dark matter (LDM), different types of interactions have been explored and allow conventional technologies to have sensitivity to DM masses that would otherwise be inaccessible. One such mechanism is inelastic scattering where an additional particle can be created in the collision, resulting in a wide parameter space of energy-momentum transfer. In this talk, I’d like to present my recent works on the ionization signals from DM-electron scattering and Migdal effects of a nuclear recoil.
Please find below the announcement for the next CAG seminar. Chih-Pan is working at the University of Montreal as post-doctoral researcher. He will share with us his recent work on dark matter.
