There are sizable differences with the analogous q\bar q configurations of a hard photon which may lead to significant phenomenological consequences on the analysis of hard processes using a forward jet probe, e.g. at the Tevatron. A geometrical interpretation of the resulting distribution in terms of black disk diffraction is proposed.Revtex file, 7pages, 3 eps figuresHigh Energy Physics - Phenomenologytext
