Jacob Leedom from DESY, Hamburg, Germany, talks about "The Sensitivity of Spin-Precession Axion Experiments" at the 17th Patras Workshop on Axions, WIMPs and WISPs.

The Patras Workshop took place at the Johannes Gutenberg University of Mainz as the second week of events within the Wavy Dark Matter Summer event series in August 2022. www.wavydarkmatter.org

Abstract:
Spin-precession experiments are the leading efforts to detect axion
dark matter interacting with nuclei. The experimental strategy is
to polarize the nuclear spin in one direction with a background
magnetic field and search for spin-precession induced by the oscillating
axion field using a sensitive magnetometer. I revisit the
experimental strategy over all hierarchies between the relevant time
scales: the axion coherence time, the integration time, and the spinrelaxation
time. The calculation reveals new features in how the
axion interacts with nuclear magnetic resonance experiments. The
results are applicable to searches for the axion coupling to nucleons,
and also the coupling to gluons, which would be responsible for
solving the strong CP problem.
