Constraint from the Lamb shift and anomalous magnetic moment on radiatively induced Lorentz andCPTviolation in quantum electrodynamics

We investigate the precisely measured anomalous magnetic moment and Lamb shift as tests for the possible existence of radiatively induced Lorentz and $\mathrm{CPT}$ violation effects in quantum electrodynamics. To this end we calculate the one-loop vacuum polarization tensor and vertex radiative cor... View More
