First Results from ABRACADABRA-10 cm: A Search for Sub-μeV Axion Dark Matter.

The axion is a promising dark matter candidate, which was originally proposed to solve the strong-CP problem in particle physics. To date, the available parameter space for axion and axionlike particle dark matter is relatively unexplored, particularly at masses m_{a}≲1 μeV. ABRACADABRA is a new exp... View More
