Laboratory bounds on electron Lorentz violation
- Department of Physics and Astronomy, University of South Carolina, Columbia, South Carolina 29208 (United States)
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 (e{sup {+-}{yields}e{+-}+{gamma}}) and photon decay ({gamma}{yields}e{sup +}+e{sup -}). 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{sub (TJ)}, at the 3x10{sup -13} to 6x10{sup -15} levels.
