# New Limits on the Lorentz/CPT Symmetry Through 50 Gravitational-wave Events

@article{Wang2021NewLO, title={New Limits on the Lorentz/CPT Symmetry Through 50 Gravitational-wave Events}, author={Ziming Wang and Lijing Shao and Chang Liu}, journal={The Astrophysical Journal}, year={2021}, volume={921} }

Lorentz invariance plays a fundamental role in modern physics. However, tiny violations of the Lorentz invariance may arise in some candidate quantum gravity theories. Prominent signatures of the gravitational Lorentz invariance violation (gLIV) include anisotropy, dispersion, and birefringence in the dispersion relation of gravitational waves (GWs). Using a total of 50 GW events in the GW transient catalogs GWTC-1 and GWTC-2, we perform an analysis on the anisotropic birefringence phenomenon…
