Covariant Quantization of CPT-violating Photons
D. Colladay, P. McDonald, J. P. Noordmans +1
We perform the covariant canonical quantization of the CPT- and Lorentz-symmetry-violating photon sector of the minimal Standard-Model Extension, which contains a general (timelike…
Test of Lorentz invariance in decay of polarized
A. Sytema, J. E. van den Berg, O. Böll +17
We search for a dependence of the lifetime of nuclei on the nuclear spin direction. Such a directional dependence would be evidence for Lorentz-invariance violatio…
Testing Lorentz Symmetry using Chiral Perturbation Theory
J. P. Noordmans
We consider the low-energy effects of a selected set of Lorentz- and CPT-violating quark and gluon operators by deriving the corresponding chiral effective lagrangian. Using this e…
Limits on Lorentz violation from charged-pion decay
J. P. Noordmans, K. K. Vos
Charged-pion decay offers many opportunities to study Lorentz violation. Using an effective field theory approach, we study Lorentz violation in the lepton, W-boson, and quark sect…
