Abstract
We analyze within the light-cone path integral
approach [12-ZLPM1] the recent CERN SPS data [12-SPS1] on
the Landau-Pomeranchuk-Migdal effect for photon bremsstrahlung
in quantum regime from 149, 207, and 287 GeV electrons.
Calculations have been carried out treating accurately the
Coulomb effects and including the inelastic processes.
Comparison with experiment is performed
accounting for multi-photon emission. Our results
are in good agreement with the data.
