title: Violation of geometric scaling in deep inelastic scattering due to Coulomb corrections.
abstract: We compute the Coulomb correction to the total and diffractive cross sections for virtual photon scattering off a heavy nucleus at low x. We show that it violates the geometric scaling in a wide range of photon virtualities and is weakly x independent. In heavy nuclei at low Q2, the Coulomb correction to the total and diffractive cross sections is about 20% and 40%, correspondingly.
