Cosmic-ray fermion decay by emission of on-shell W bosons with CPT violation

Autor: Robertus Potting, J. P. Noordmans, Don Colladay

Publikováno v: Physical Review D. 96

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-violating and CPT-odd Chern-Simons like parameter for the W boson, which i

Lorentz invariance in the weak interaction has been tested rather poorly compared to the electromagnetic interaction. In this work we show which tests on the weak interaction should be considered. We focus on one particular test that explores the spi

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, lightlike, or spacelike) fixed background tensor $k_{AF}^\mu$. Well-

General relativity and the standard model are invariant under Lorentz transformations. Lorentz invariance violation is one manifestation of $C\phantom{\rule{0}{0ex}}P\phantom{\rule{0}{0ex}}T$ violation. Weak interactions violate discrete symmetries (

Possibilities to test the Lorentz invariance of the weak interaction in muon decay are considered. We derive the direction-dependent muon-decay rate with a general Lorentz-violating addition to the W-boson propagator. We discuss measurements of the d
