Title: Probing the Dark Universe for Axions

Speaker: Rakshya Khatiwada, University of Washington

 

Abstract: The QCD axion is a weakly interacting sub-eV mass particle. It is also a good cold dark matter candidate and if discovered could explain the long-standing strong CP problem. The Axion Dark Matter eXperiment (ADMX) is one of the three DOE “Generation-2” direct dark matter searches and the only one dedicated to finding the QCD axion. In 2017 ADMX achieved sensitivity to the very compelling DFSZ (“GUT”) axion, a decades-long goal of axion experimenters. This talk will focus on this result along with the recent upgrades, including the dilution refrigerator operating at 90mK, the state-of-the-art quantum electronics and new techniques used to obtain these results. There will also be a discussion on landscape of future of axion searches.
