Laboratory Bounds on Electron Lorentz Violation

Understand

Violations of Lorentz boost symmetry in the electron and photon sectors can be constrained by studying several different high-energy phenomenon.

• Although they may not lead to the strongest bounds numerically, measurements made in terrestrial laboratories produce the most reliable results.
• Laboratory bounds can be based on observations of synchrotron radiation, as well as the observed absences of vacuum Cerenkov radiation.
• Using measurements of synchrotron energy losses at LEP and the survival of TeV photons, we place new bounds on the three electron Lorentz violation coefficients c_(TJ), at the 3 x 10^(-13) to 6 x 10^(-15) levels.
