Fully quantum treatment of the Landau-Pomeranchuk-Migdal effect in QED and QCD
Zakharov B.G.
For the first time a rigorous quantum treatment of the Landau-Pomeranchuk-Migdal effect in Q£D and QCD is given. The rate of photon (gluon) radiation by an electron (quark) in medium is expressed through the Green's function of a two-dimensional Schrodinger equation with an imaginary potential. In QED this potential is proportional to the dipole cross section for scattering of e+e- pair off an atom, in QCD it is proportional to the cross section of interaction with color centre of the color singlet quark-antiquark-gluon system.
