  High energy hadronic interactions can produce a final state characterized by
minijets separated by a large gap in the rapidity distribution of the produced
secondary particles. We discuss the process by keeping into account the
possibility of having multiple parton collisions in the hadronic interaction.
At Tevatron energy the correction to the single scattering term induced by the
presence of multiparton interactions is large for transverse momenta smaller
than 6 GeV.
