  We demonstrate that underlying assumptions concerning the structure of
constituent parton Fock states in hadrons make a strong impact on the
predictions of hadronic interaction models for forward hadron spectra and for
long-range correlations between central and forward hadron production. Our
analysis shows that combined studies of proton-proton collisions at the Large
Hadron Collider by central and forward-looking detectors have a rich potential
for discriminating between the main model approaches.
