Title: Testing DAMA's Long-standing Claim for Dark Matter Detection
Host: Jim Alexander
Abstract: Astrophysical observations give overwhelming evidence for the existence of dark matter. Several theoretical particles have been proposed as dark matter candidates, including weakly interacting massive particles (WIMPs), axions, and more recently, their much lighter counterparts. However there has not yet been a definitive detection of dark matter. One group, the DAMA collaboration, has asserted for years that they observe a dark matter-induced annual modulation signal in their NaI(Tl)-based detectors. Their observations seem to be inconsistent with those from other direct detection dark matter experiments under most assumptions of dark matter. In this talk I will describe the current status of the debate and the world-wide experimental effort to test this extraordinary claim. I will report the recent results from the COSINE-100 experiment and our progress toward resolving the current stalemate in the field.
This talk will be given via Zoom, and the link is emailed to the Physics listserv the week of the talk. If you are not on the listserv, please contact Sue Sullivan at email@example.com by Monday at 3:00 pm to request the link.
