Testing Relativity using Precision Measurements
Lorentz and CPT symmetry is one of the most important foundations of Einstein's relativity. Tests of this symmetry have experienced a revival in recent years, stimulated by the possibility that minuscule violations could arise from a unification of quantum physics with gravity such as string theory. This talk explores the theoretical and experimental prospects for Lorentz violation, focusing on electromagnetic interactions. The theory of Lorentz violation in quantum electrodynamics is presented, and experimental observables are established for precision experiments involving confined particles and antiparticles. Constraints on coefficients for Lorentz and CPT violation from existing data will be presented and prospective sensitivities in future experiments will be outlined. Suitable projects that are accessible to undergraduates will also be discussed.
