Experimental results on diffractive one-pion production at the CERN ISR
New experimental results are reported on diffractive dissociation of protons into (n pi /sup +/) in proton-proton collisions at a centre- of-mass energy of square root s=45 GeV. The data were obtained using the Split-Field-Magnet detector at the CERN Intersecting Storage Rings. The authors have sear...

| description | New experimental results are reported on diffractive dissociation of protons into (n pi /sup +/) in proton-proton collisions at a centre- of-mass energy of square root s=45 GeV. The data were obtained using the Split-Field-Magnet detector at the CERN Intersecting Storage Rings. The authors have searched for resonance contributions and found peaks at mass values of 1.5 GeV, 1.65 GeV, and 2.1 GeV. A dip in d sigma /dt is observed at low t and low mass; it is most pronounced for events with neutrons emitted at 90 degrees in the Gottfried-Jackson frame. The correlation between mass and slope depends strongly on theta /sub J/. The cross section of the channel pp to pn pi /sup +/ is 440+or-110 mu b at square root s=45 GeV, giving an energy dependence of s/sup -0.30+or-0.07/ for isospin exchange zero in this channel.
