The semiclassical Baïer-Katkov (BK) formula is an approximation to the spectrum of the radiation by an ultrarelativistic electron in a nonuniform field, taking into account the recoil and spin effects. The question why it involves only the initial e

The characteristics of the electron-photon showers initiated by 2 to 10 GeV electrons aligned along the ⟨111⟩ axis of tungsten crystals are compared with those for the amorphous tungsten. In this energy range, as known, the positron yield at the

Particles traveling in aligned crystals at small angles w.r.t. crystallographic axes or planes are principally steered by the continuous Lindhard potential. This interaction conserves the energy E, the longitudinal momentum p_parallel, the transverse

We revisit the recursive model for the fragmentation of polarized quarks based on the string $+{^{3}P}_{0}$ mechanism of $q\overline{q}$ pair creation. We make a different choice for one input function of the model that simplifies the implementation

International audience; The strong dependence of the PXR yield on the orientation of the crystal surface, claimed in a recent article by S. Blazhevich and A. Noskov, is questioned. It is argued that, if absorption is neglected, the sum of the ordinar

Several estimators of the initial transverse polarization of a quark fragmenting into a jet are proposed and compared using Monte Carlo simulations. These are based on the simplified version of a recursive model [A. Kerbizi et al, Phys. Rev. D97, 074

In a crystal, thermal vibrations of neighboring atoms are correlated: long wavelength phonons make them displace in the same direction. These correlations can speed up the dechanneling of axially channeled particles, as shown by a simulation with bin
