On the Possibility of the Strong Field QED Investigation at LHC
V. G. Baryshevsky, V. V. Tikhomirov
Abstract
The interaction of high energy particles with atomic axes and planes allows to observe in crystal various effects predicted by the 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 in crystals allowing to observe vacuum dichroism and birefringence, electron radiative self-polarization and polarized electron-positron pair production by gamma-quanta, positron (electron) anomalous magnetic moment modification and electron spin rotation in crystal field harmonics. The effect of vacuum birefringence induced by strong electric field is considered in detail.
