Abstract

The electrodynamical formulae for the transition radiation are applied to the case of partons crossing the surface of the deconfined region in heavy ion collisions. The chromopermittivity is used in place of the dielectric permittivity. The corresponding energy-angular distributions of emitted gluons are discussed. They could be of interest at LHC energies.
