  author={Konstantin Goulianos},
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 triplepomeron 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… CONTINUE READING
