High Energy Physics Seminar
The presence of dark matter provides some of the most persuasive evidence for the existence of physics beyond the Standard Model. One compelling dark matter candidate is the axion, a light boson that was originally postulated as a solution to another outstanding issue, the strong CP problem in QCD. This talk discusses direct searches for low-mass axion dark matter. The prototype experiment, ABRACADABRA-10 cm, developed the innovative lumped-element detection method and set world-leading limits on axions. It also set the stage for the DMRadio program, a series of larger detectors that will be capable of finding axions or definitively excluding them over a large range of masses below 1 μeV. Here I present the status and upcoming plans for DMRadio-50L, which is currently under construction, DMRadio-m^3, which is in design, and DMRadio-GUT, a future large-scale experiment.
The talk is in 469 Lauritsen.
