Hydrogen and Antihydrogen Spectroscopy for Studies of CPT and Lorentz Symmetry
Robert Bluhm, Alan Kostelecky, Neil Russell
A theoretical study of possible signals for CPT and Lorentz violation arising in hydrogen and antihydrogen spectroscopy is described. The analysis uses a CPT- and Lorentz-violating…
Testing CPT and Lorentz Symmetry with Electrons and Positrons in Penning Traps
Robert Bluhm, Alan Kostelecky, Neil Russell
We present a theoretical analysis of signals for CPT and Lorentz violation in g-2 and charge-to-mass-ratio experiments on electrons and positrons in Penning traps. Experiments meas…
CPT and Lorentz Tests in Hydrogen and Antihydrogen
Robert Bluhm, Alan Kostelecky, Neil Russell
Signals for CPT and Lorentz violation at the Planck scale may arise in hydrogen and antihydrogen spectroscopy. We show that certain 1S-2S and hyperfine transitions can exhibit theo…
Sensitivity of CPT Tests with Neutral Mesons
Alan Kostelecky
The sensitivity of experiments with neutral mesons to possible indirect CPT violation is examined. It is shown that experiments conventionally regarded as equivalent can have CPT r…
CPT and Lorentz Tests in Penning Traps
Robert Bluhm, Alan Kostelecky, Neil Russell
A theoretical analysis is performed of Penning-trap experiments testing CPT and Lorentz symmetry through measurements of anomalous magnetic moments and charge-to-mass ratios. Possi…
Lorentz-Violating Extension of the Standard Model
Don Colladay, Alan Kostelecky
In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal SU(3) x SU(2) x U(1) standard model including CPT-even and CPT-…
