# Cosmological Background torsion limits from Lorentz violation

@article{Andrade2001CosmologicalBT, title={Cosmological Background torsion limits from Lorentz violation}, author={luiz Garcia de Andrade}, journal={arXiv: High Energy Physics - Theory}, year={2001} }

Cosmological limits on Lorentz invariance breaking in Chern-Simons $(3+1)-dimensional$ electrodynamics are used to place limits on torsion. Birefrigence phenomena is discussed by using extending the propagation equation to Riemann-Cartan spacetimes instead of treating it in purely Riemannian spaces. The parameter of Lorentz violation is shown to be proportional to the axial torsion vector which allows us to place a limit on cosmological background torsion from the Lorentz violation constraint…
