Using a secondary pion beam from the Argonne Zero Gradient Synchrotron we have studied the process π−p→φn in the region of the cross-section enhancement near kinematic threshold. For incident momenta between 1.6 and 2 GeV/c, we have determined production and decay angular distributions and extrapolated total cross sections from a sample of about 160 φ's above background. The production and decay distributions are consistent with isotropy over this entire incident-momentum range. The extrapolated total cross section varies between 19 and 25 μb.

Nonstrange Resonance Production in pi+ p Collisions at 2.35, 2.62, and 2.90 GeV/c

In an exposure of the Brookhaven National Laboratory 20-in. hydrogen bubble chamber to a separated π+ beam at π+ momenta of 2.35 BeV/c (center-of-mass energy E*=2.30 BeV), 2.62 BeV/c (E*=2.41 BeV), and 2.90 BeV/c (E*=2.52 BeV), we have observed production of the ω0, ρ0, and η0 mesons. The production of the ω0, ρ0, and η0 is often accompanied by simultaneous production of the N*++. The momentum transfer in ω0 and ρ0 production is characteristic of peripheral collisions and suggests a single-particle exchange for the production mechanism. The decay distributions for the ω0, ρ0, and the ρ+ demonstrate the importance of modifying the single-particle-exchange model to include absorptive effects. An upper limit on the two-π decay of the ω0 is set at 2%. The width of the η0 is found to be less than 10 MeV. Elastic-scattering distributions are presented.

Single Pion Production in pi- p Collisions at 2.14 GeV/c

Hagopian, V. ; Pan, Y.L. ;
Phys.Rev. 152 (1966) 1183, 1966.
Inspire Record 50984 DOI 10.17182/hepdata.26635

A bubble-chamber experiment in which the reaction π−+p→π+π+N was studied at a beam momentum of 2.14 BeV/c yielded 1533 and 2234 events of the final states π−π0p and π−π+n, respectively. These events are dominated by the formation of the ρ resonance, which is produced mostly in the forward direction. Both the production and decay angular distributions of the ρ− agree very well with the predictions of the one-pion exchange theory modified by absorption effects. The decay angular distribution of the ρ0 shows the well-known forward-backward asymmetry. This effect is interpretable as the result of the interference between the ρ0 and an isospin-zero s-wave π−π resonance. The production of the ρ0, in addition to its forward peak, shows a weak backward peak. Partial cross sections of various final states are also presented.

The π − p→ ωω n reaction has studied for the first time at the 70 GeV IHEP accelerator. The six photons from the decay of the two ω mesons were detected in GAMS-2000, a hodoscope multi-photon spectometer. Two resonances decaying into ωω,X (1640) and X(1960), have been observed. Their quantum numbers are J PC =2 ++ , I G =0 + . The reaction is dominated by the one-pion exchange mechanism. The production cross sections σ. BR(X→ ωω ) are 0.65±0.15 μ b and 1.0±0.2 μ b, respectively.
