About this document
Lorentz Violation in Gravitational Waves by argkau is a document available to read on EtoBox.
This paper investigates a model where Lorentz symmetry is broken via extrinsic curvature terms in gravity, leading to scale-dependent damping in gravitational wave propagation. Using NANOGrav and IPTA data, the authors set a new lower bound on the Lorentz-violating energy scale MLV > 10⁻¹⁹ GeV, improving previous LIGO/VIRGO results. This work is valuable for researchers studying quantum gravity, fundamental symmetries, and modifications to general relativity.
