Factorization and scaling in hadronic diffraction

A comprehensive analysis of single diffraction dissociation data on $p\left(\overline{p}\right)+\overrightarrow{p}p\left(\overline{p}\right)+X$ from fixed target to collider energies reveals a striking breakdown of factorization, which does not affect the shape of the $M_X^2$ dependence of the differential cross sections. Phenomenologically, this result can be obtained by postulating a scaling law for hadronic diffraction, which is embedded in the hypothesis of Pomeron flux renormalization introduced to unitarize the triple-Pomeron amplitude.
