Inclusive Double-Pomeron Exchange at the Fermilab Tevatron p¯p Collider (original) (raw)

This study presents a measurement of the inclusive double Pomeron exchange (DPE) in proton-antiproton collisions at the Tevatron collider with a center-of-mass energy of 1800 GeV. The analysis focuses on events with a leading antiproton experiencing a fractional momentum loss and evaluates the behavior of the proton fractional momentum loss distribution in the context of double Pomeron exchange. Notably, the fraction of events with low momentum loss indicates significant contributions from DPE processes, which were analyzed in comparison to single diffractive and non-diffractive dijet production rates. The results show a large DPE contribution, thus providing crucial constraints for theoretical models and enhancing the understanding of rapidity gaps in high-energy particle physics.
