Abstract: | A comparison of the electron and positron anomalous magnetic moments has been performed using the resonance depolarization method for the VEPP-2M storage ring beams. It has been shown, that the difference between anomalous magnetic moments of electron and positron doesn't exceed 1.0 × 10?5 with 95% confidence level in agreement with CPT-theorem prediction on equality of the particle and antiparticle magnetic moments. The achieved accuracy is two orders better than that available up to now. |
