关于在LHC进行强场QED研究的可能性
On the Possibility of the Strong Field QED Investigation at LHC
摘要:
高能粒子与原子轴和平面的相互作用允许在晶体中观察强电磁场中现象的量子电动力学预测的各种效应。特别地,在半均匀场中由伽马量子产生的电子-正电子对的效应在80年代首次在CERN的锗晶轴领域中被观察到。LHC的高能量极大地拓宽了强场QCD效应在晶体中研究的可能性,允许观察真空二向色性和双折射,电子辐射自极化和由γ量子产生的极化电子-正电子对,正电子(电子)反常磁矩修改和晶体场谐波中的电子自旋旋转。详细考虑了强电场引起的真空双折射效应。
英文摘要:
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.
