AbstractThe possibility of anisotropies in the speed of light relative to the limiting speed of electrons is considered. The absence of sidereal variations in the energy of Compton-edge photons at the ESRF’s GRAAL facility constrains such anisotropiesrepresenting the first non-threshold collision-kinematics study of Lorentz violation. When interpreted within the minimal Standard-Model Extension,this result yields the two-sided limit of 1.6 x 10^{-14} at 95 % confidence level on a combination of the parity-violating photon and electron coefficients
