Cosmic-ray fermion decay through tau-antitau emission with Lorentz violation
C. A. Escobar, J. P. Noordmans, R. Potting
We study CPT and Lorentz violation in the tau-lepton sector of the Standard Model in the context of the Standard-Model Extension, described by a coefficient which is thus far unbou…
CPT and Lorentz violation en the Photon and -boson sector
D. Colladay, J. P. Noordmans, R. Potting
CPT and Lorentz violation in the photon sector is described within the minimal Standard-Model Extension by a dimension-3 Chern-Simons-like operator parametrized by a four-vector pa…
Cosmic-ray fermion decay by emission of on-shell W bosons with CPT violation
D. Colladay, J. P. Noordmans, R. Potting
We study CPT and Lorentz violation in the electroweak gauge sector of the Standard Model in the context of the Standard-Model Extension. In particular, we consider the Lorentz-viol…
Gluonic Lorentz violation and chiral perturbation theory
J. P. Noordmans
By applying chiral-perturbation-theory methods to the QCD sector of the Lorentz-violating Standard-Model Extension, we investigate Lorentz violation in the strong interactions. In…
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…
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…
