Description

The reaction pp → ppπ+π- at √s = 31 GeV was studied at the Split Field Magnet Facility of the CERN-ISR. Selecting events with two leading protons of x > 0.9 and a rapidity gap Δy > 2 between the protons and both pions a sample of 720 events is obtained representing a cross section of 25 +- 10 μb. The mass distribution of the dipion system, x and psub(T) distributions for the protons are presented and analyzed for the presence of double pomeron exchange. (Auth.)
