Lorentz Violation and Vector Meson Dominance
Abstract
Vector meson dominance models describe the mixing of photons with vector mesons; the hadronic admixture frequently dominates the interactions of photons with nucleons. This mixing also makes it possible to test for new physics affecting the vector mesons using photon measurements. The possibilities for new physics to be contrained in this indirect fashion include potential Lorentz and CPT violations in the hadronic effective action. The characteristic scale of bounds on Lorentz violation coefficients in the ρ0 meson sector is two orders of magnitude weaker than the corresponding photon bounds, three orders of magnitude weaker for ϕ vector mesons, and four orders of magnitude weaker for ω mesons.

AB - Vector meson dominance models describe the mixing of photons with vector mesons; the hadronic admixture frequently dominates the interactions of photons with nucleons. This mixing also makes it possible to test for new physics affecting the vector mesons using photon measurements. The possibilities for new physics to be contrained in this indirect fashion include potential Lorentz and CPT violations in the hadronic effective action. The characteristic scale of bounds on Lorentz violation coefficients in the ρ^0 meson sector is two orders of magnitude weaker than the corresponding photon bounds, three orders of magnitude weaker for ϕ vector mesons, and four orders of magnitude weaker for ω mesons.
