• It is shown that the infrared divergences in quark-quark scattering process with a hard photon in the state vanish in the cross section summed over degenerate initial states as well as final ones. All the diagrams with an arbitrary number of disconnected soft gluons must be taken into account, but the contributions of disconnected parts can be factored out by a rearrangement of the infinite series. A finite number of connected diagrams are added to give an infrared finite result.
