Investigating Lorentz and CPT Symmetry with Antihydrogen
This talk discusses theoretical aspects of tests of CPT and Lorentz Symmetry that will in principle be possible with trapped antihydrogen. The framework is the standard-model extension, which admits minuscule violations of CPT and Lorentz symmetry in a general manner without giving up other features of the standard model of particle physics. Spectroscopic transitions in hydrogen and antihydroge...
متن کاملCpt and Lorentz Symmetry in Hydrogen and Antihydrogen A
Possibilities for observing signals of CPT and Lorentz violation in the spectroscopy of hydrogen and antihydrogen are considered. We show that transitions between the c and d hyperfine sublevels in the 1S state can exhibit theoretically detectable effects that would be unsuppressed by powers of the fine-structure constant. This transition may therefore offer some advantages over 1S-2S two-photo...
متن کاملSensitivity of CPT Tests with Neutral Mesons
Neutral-meson interferometry is a powerful tool for investigating the discrete symmetry CPT. This product of charge conjugation C, parity reflection P, and time reversal T is known to be an invariance of local relativistic quantum field theories of point particles in flat spacetime [1]. Among the various tests of CPT [2], the sharpest published bounds are obtained with the neutralkaon system. A...
متن کاملCharm-system Tests of Cpt with Focus
We discuss a search for CPT violation in neutral charm meson oscillations. The data come from the Fermilab fixed-target experiment FOCUS. While flavor mixing in the charm sector is predicted to be small by the standard model, it is still possible to investigate CPT violation through study of the proper time dependence of the asymmetry in right-sign decay rates for D0 and D̄0. Using present limit...
متن کاملCPT and lorentz tests with muons
Precision experiments with muons are sensitive to Planck-scale CPT and Lorentz violation that is undetectable in other tests. Existing data on the muonium ground-state hyperfine structure and on the muon anomalous magnetic moment could be analyzed to provide dimensionless figures of merit for CPT and Lorentz violation at the levels of 4x10(-21) and 10(-23).
