• We report here the first experimental result for the anisotropy of the one-way maximum attainable speed of the electron, Δc→1,e, obtained via the study of a sidereal time dependence of the difference between momenta of the counterrotating electron and positron beams in the Cornell Electron Storage Ring at Cornell University. At 95% confidence, an upper limit for the component of Δc→1,e/c perpendicular to Earth's rotational axis is found to be 5.5×10−15.
