Applied Physics/Physics Colloquium: Searching for Dark-Matter Axions

Topic: 
Searching for Dark-Matter Axions
Tuesday, April 7, 2015 - 4:00pm to 5:15pm
Venue: 
Hewlett 201
Speaker: 
Leslie Rosenberg (University of Washington)
Abstract / Description: 

The axion is a hypothetical elementary particle whose existence would explain the baffling absence of CP violation in the strong interactions. Axions also happen to be a compelling dark-matter candidate. Even if dark-matter axions were to comprise the overwhelming majority of mass in the universe, they would be extraordinarily difficult to detect. However, several experiments, either under construction or taking data, would be sensitive to even the more pessimistically coupled axions. This talk describes the current state of these searches.
