NPA Seminar: Chelsea Bartram, SLAC, “A Bird’s Eye View of Dark Matter”

Evidence for the existence of dark matter abounds in the study of astrophysical phenomena. Nevertheless, a dark matter candidate has yet to be explicitly identified. Direct detection of such a particle would point to physics beyond the Standard Model. The Axion Dark Matter eXperiment (ADMX) is searching for a wave-like dark matter candidate in the form of an axion. Such a candidate could resolve not only the dark matter problem, but also the strong CP problem. I will present recent progress made by the ADMX collaboration in the pursuit of the DFSZ axion, as well as plans for future searches at higher frequencies (larger axion masses). I will also describe the challenges facing axion searches, and put forward new ideas for performing broadband experiments, enabling faster coverage of the wide-open parameter space.
There will be a luncheon with the speaker from 12-1 p.m. in WLC-245. Lunch will be provided for people on a first-come, first-served basis for people who RSVP by Wednesday, August 17th: https://tinyurl.com/npa-signup
