We report results from a study of events with a leading antiproton of beam momentum fraction 0.905<x(F)<0.965 and 4-momentum transfer squared |t|<3 GeV2 produced in &pmacr;p collisions at sqrt[s] = 1800 GeV at the Fermilab Tevatron collider. Approximately 2% of the events contain two jets of transverse energy E(jet)(T)>7 GeV. Using the dijet events, we evaluate the diffractive structure function of the antiproton and compare it with expectations based on results obtained in diffractive deep inelastic scattering experiments at the DESY ep collider HERA.
我们报告了在费米实验室万亿电子伏特加速器（Tevatron collider）进行的质心能量√s = 1800 GeV的质子-反质子（p̅p）对撞中，对束流动量分数0.905 < x(F) < 0.965且四动量转移平方|t| < 3 GeV²的事件进行研究的结果。约2%的事件包含两个横向能量E(jet)(T) > 7 GeV的喷注。利用双喷注事件，我们评估了反质子的衍射结构函数，并将其与基于在德国电子同步加速器（DESY）的正负电子对撞机HERA上进行的衍射深度非弹性散射实验结果所得到的预期进行比较。
