Abstract
Absorptive effects in hard-scattering processes, which can possibly originate from multiparton final-state interactions, give rise to a vanishingly small logarithmic correction to the parton → parton + parton splitting process, if simulated by Regge amplitudes. When this effect is iterated, within the leading logarithmic approximation of quantum chromodynamics, it may be promoted to a small power correction to the structure (or fragmentation) functions and be observable at very high energies.
