Strong Field QED at LHC: Vacuum Birefringence.
V.G.Baryshevsky, S.E.Siahlo, and V.V.Tikhomirov

The interaction of high energy particles with atomic axes and planes allows to observe in crystal various effects predicted by quantum electrodynamics of phenomena in strong electromagnetic field. In particular, the effect of electron-positron pair production by gamma-quanta in a semi-uniform field was observed for the first time in eightieth in CERN in the field of germanium crystal axes. The high energy of LHC drastically widens the possibilities of strong field QCD effect investigation allowing to observe the effects of vacuum dichroism and birefringence, of electron self-polarization and polarized electron-positron pair production by gamma-quanta, of positron (electron) anomalous magnetic moment modification, and of electron spin rotation in a circularly polarized electromagnetic wave in the field of crystal planes. The nonlinear effect of vacuum birefringence induced by strong electric field is considered in detail.
Key words: QED, strong fields, high energies, crystals, LHC, vacuum birefringence
