Topic: Am Expansive Search for Dark Matter with ADMX and DM Radio
 
Abstract:
One of the most well-motivated dark matter candidates is the axion, a particle that is predicted by the solution to another long-standing mystery in physics, the strong CP problem. An established axion search technique leverages the Inverse Primakoff effect by which an axion converts to a photon in a magnetic field. This so-called ‘photon channel’ can be probed using an ‘axion haloscope’ which consists of an exquisitely sensitive receiver chain in a strong magnetic field. Recent work has further advanced the theoretical motivation for axions over a wide range of masses. 

The Axion Dark Matter eXperiment (ADMX) implements one form of haloscope that relies on a microwave cavity. Previously, the ADMX collaboration has searched for axions at DFSZ sensitivity from 950-1020 MHz and two times DFSZ sensitivity from 800-950 MHz. Preliminary results from a more recent search will be presented, as well as plans to cover from 1020 to 1350 MHz with the next data-taking run. 

 

 

At low masses, O(0.1-100neV), a promising search technique uses a lumped-element detector.  A prototype experiment, ABRACADABRA-10cm, demonstrated the viability of the lumped-element approach and set world-leading limits on low-mass axions. The DMRadio program will extend the technique with a series of larger, more sensitive detectors that will be capable of probing QCD axions and axion-like particles over a wide range of masses below 1 μeV
