Lorentz Invariance Breakdown and Constraints from Big-Bang Nucleosynthesis
arXiv:astro-ph/0510386 · doi:10.1103/PhysRevD.72.087702
Abstract
The Standard Model Extension formulated by Colladay and Kostelecký is reviewed in the framework of the primordial abundance. Upper bounds on coefficients for the Lorentz violation are derived using the present observational data.
