Title: Testing gravity on accelerators
Abstract: In this talk I will introduce several methods of testing the weak equivalence principle with the use of modern particle accelerators. Predictions of the general relativity (GR) for the high-energy particles and/or the antimatter were never confirmed experimentally, which is the main motivation for my work. I will show that the absence of the vacuum Cherenkov radiation at LEP and photon stability for the Tevatron experiments confirm validity of GR for high-energy electrons and positrons at 4% level. High precision measurements of the synchrotron losses at LEP reduce this figure to 0.1%. I will also comment on a possibility of improving the limits in the Compton scattering experiments at the future ILC and CLIC colliders.
