High Energy Physics Seminar

­*New date*

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.
