摘要：

We have measured the absolute cross section for dimuon production in hadron collisions at 200 GeV/c in the continuum region M = 4-8.5 GeV. In all the channels studied (pN, pN, π±N and π-H2) the experimental cross section is significantly larger by a factor of 2.3 ± 0.5 than expected from the Drell-Yan model. Furthermore, our proton-nucleon data allow a determination of the nucleon valence structure function which agrees with the deep inelastic lepton scattering data. © 1979.
