We report the first observation of dijet events with a double Pomeron exchange topology produced in &pmacr;p collisions at sqrt[s] = 1800 GeV. The events are characterized by a leading antiproton, two jets in the central pseudorapidity region, and a large rapidity gap on the outgoing proton side. We present results on jet kinematics and production rates, compare them with corresponding results from single diffractive and inclusive dijet production, and test factorization.
我们报告了在√s = 1800 GeV的p̅p碰撞中产生的具有双Pomeron交换拓扑的双喷注事件的首次观测结果。这些事件的特征是一个领头反质子、中心赝快度区域的两个喷注以及出射质子一侧的大快度间隙。我们给出了喷注运动学和产生率的结果，将它们与单衍射和包容性双喷注产生的相应结果进行比较，并检验因子分解。
