在M=4-8.5GeV的连续区，我们测量了200GeV/c强子碰撞中双子产生的绝对截面。在所有被研究的通道(Pn，p N，π±N和π−H2)中，实验截面比Drell-yan模型的预期大2.3±0.5倍。此外，我们的质子-核子数据允许确定核子价结构函数，这与深度非弹性轻子散射数据相一致。
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, p N, 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.
