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.
The feasibility studies of the measurement of the central exclusive jet production at the LHC using the proton tagging technique are presented. In order to reach the low jet-mass region, single tagged events were considered. The studies were performe
We investigate the 2nd order process of two photons being emitted by a high-energy electron dressed in the strong background electric field found between the planes in a crystal. The strong crystalline field combined with ultra relativistic electrons
We analyze the phenomenology of the top-pion and top-Higgs states in models with strong top dynamics, and translate the present LHC searches for the Standard Model Higgs into bounds on these scalar states. We explore the possibility that the new stat
QED perturbation theory has been conjectured to break down in sufficiently strong backgrounds, obstructing the analysis of strong-field physics. We show that the breakdown occurs even in classical electrodynamics, at lower field strengths than previo
The problem of X-ray Free-Electron Laser operating on self-amplified spontaneous emission in irregular microundulator is considered. The case when the spectrum width of spontaneous radiation is conditioned by the spatial distribution of sources creat
