We have studied the reactions π+n→K+K−p, π+p→K+K−Δ++, and π+p→(K+K−π+)p in 10-GeV/c π+d interactions using the large-aperture solenoid spectrometer at SLAC. We measure the cross sections times branching ratios for the production of the known meson resonances f(1270), g(1690), and h(2040). We also observe a new resonance with mass 2747±32 MeV, width 195±75 MeV, and production cross section times branching ratio into K+K−π+ of 0.84±0.08 μb. The data are consistent with the quantum numbers of this state being I=1, JP=7−.

Partial, Total, and Resonance Production Cross-Sections for the Reactions pi+ p --> Four Prong Final States at 10.3-GeV/c

The major production channels of four-prong final states resulting from π+p interactions at a center-of-mass energy of 4.5 GeV are studied. In addition to total production cross sections, comprehensive listings of partial and resonance production cross sections are also given for each final state of interest. All final states, including nπ+π+π+π−, are found to exhibit copious resonance production.
