Diffractive hadroproduction of dijets and W's at the Fermilab Tevatron collider and the Pomeron structure function

Results from a phenomenological analysis of dijet and W hard diffractive hadroproduction at Fermilab Tevatron energies are reported. The theoretical framework employed here is a modified version of the Ingelman-Schlein approach which includes Dokhshitzer-Gribov-Lipatov-Altarelli-Parisi-evolved structure functions. Different from what has been achieved by the DESY ep HERA reactions, a reasonable overall description of such diffractive hadron processes is obtained only when a complex, quark-rich Pomeron structure function is employed in the calculation
