Tests of Spacetime Symmetry with Particle Traps
Neil Russell
Lorentz and CPT symmetry have been tested at high precision in numerous experiments. A general theoretical framework incorporating possible Lorentz and CPT violation in an extensio…

Searching for Lorentz Violation in the Ground State of Hydrogen
Robert Bluhm, V. Alan Kostelecky, Neil Russell
A theoretical analysis is made of experiments in hydrogen and antihydrogen that test CPT. We show that these experiments also provide sensitive tests of Lorentz symmetry for proton…

Bounding CPT- and Lorentz-Violating Parameters in a Standard-Model Extension
Neil Russell
A general theoretical framework that incorporates possible CPT and Lorentz violation in an extension of the standard model and in quantum electrodynamics has been developed over th…
