Electromagnetic Tests of Lorentz and CPT Symmetry
R. Bluhm
A review is presented of some recent Lorentz and CPT tests in atomic and particle systems where the predominant interactions are described by quantum electrodynamics. A theoretical…
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…
Theoretical Analysis of CPT and Lorentz Tests in Penning Traps
Robert Bluhm
The CPT theorem has been tested to very high precision in a variety of experiments involving particles and antiparticles confined within Penning traps. These tests include comparis…
Tests of CPT and Lorentz Symmetry in Penning-Trap Experiments
Robert Bluhm, Alan Kostelecky, Neil Russell
This talk discusses the sensitivity of electron-positron and proton-antiproton Penning-trap experiments to CPT- and Lorentz-violating effects in the context of an extension of the…
