The additive quark model revisited: hadron and photon induced cross-sections
P. Desgrolard, M. Giffon, E. Martynov, E. Predazzi
Abstract
The standard additive quark model and the ensuing counting rules are modified to take into account the quark-gluonic content of the Pomeron and of the secondary Reggeons. The result is that a much improved description of pp, πp, γp and γγ cross-sections is achieved.
