Abstract

While the main features of elastic, diffractive and total cross sections are described well by Regge theory, the measured rise of the proton-(anti)proton single diffraction dissociation cross section with energy is considerably smaller than the theoretical prediction based on factorization and a constant triple-pomeron coupling. The observed energy dependence is obtained by renormalizing the pomeron flux "carried" by a nucleon to unity. Double diffraction and double pomeron exchange cross sections are reevaluated and compared to data, and a new interpretation of hard diffraction results emerges in which the hard pomeron obeys the momentum sum rule.
