Abstract
Multiple-core production in hadron-hadron collisions directly measures (in the context of the parton model) differential cross sections for parton-parton collisions. To obtain ∼20% accuracy in reconstruction of the parton-parton kinematics requires transverse momentum of the cores ≳ 5 GeV/c. Experiments at NAL as well as the CERN ISR appear feasible. What might be learned from such studies is discussed.
