Magnetic Moments of Electrons and Positrons
In this report we describe a number of new features in our precision experiments currently in progress to measure the anomalous magnetic moments of the electron and positron, and we will point out the impact these improvements will have in testing several fundamental theories in physics. In the electron experiment, reduction in both statistical and systematic errors will result in a comparison with QED predictions at the level of the eighth-order term in the expansion of the anomaly in powers of α. In addition, by varying the energy of the electrons we can test special relativity to an accuracy of 2×10-11. The positron experiment will test CPT by comparing the electron and positron magnetic moments.
