We argue that such a measurement of diffractive jets could help understanding if at the present energies, unitarity comes as a consequence of saturation.4 pages, 3 figures, Proceedings of the XIth International Conference on Elastic and Diffractive Scattering (EDS05), Blois, France, May 15-20 2005High Energy Physics - Phenomenologytext
