Description of the CERN SPS data on the Landau-Pomeranchuk-Migdal effect for photon bremsstrahlung in quantum regime

Abstract

We analyze within the light-cone path integral approach [4] the recent CERN SPS data [19] 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.
