The magnetic dipole moment of the muon (gμ) quantifies its intrinsic magnetism, determined from its coupling strength to the photon. To first order, gμ = 2. The anomalous magnetic dipole moment of the muon (aμ) is the additional magnetism that arises from virtual corrections.
The experiment directly measures this anomalous part, hence the name g-2. It does this by storing muons at a specific energy in a uniform magnetic field, and measuring the number of decays and the direction of the emitted decay particles, which oscillates in time at a frequency proportional to aμ. The experiment ran from 2017 until 2023, and recorded the decay of over 100 billion muons. The data from these decays are still being analysed.
The team at Liverpool University designed, built and installed the tracking detectors for the experiment, has a strong involvement in all areas of analysis for both the headline g-2 measurement as well as the measurement of the muon's electric dipole moment, including the tracking-based beam dynamics analysis and the precession frequency and magnetic field measurements.
The group's research work on g-2 is strongly supported by the Science and Technology Research Council and the Leverhulme Trust.
