| Abstract: | The observed p⊥ distributions of large mass muon pairs produced in proton-nucleus collisions are quantitatively explained in QCD by also explicitly taking into account the intrinsic wave function p⊥ spread of partons inside the hadrons. The experimental data indicate 〈p⊥〉 ～ 500–600MeV for each parton. |
