Measurement of Polarization in pi-p Elastic Scattering from 229 to 390 MeV

Arens, John F. ; Chamberlain, Owen ; Dost, Helmut E. ; et al.
Phys.Rev. 167 (1968) 1261-1267, 1968.
Inspire Record 944940 DOI 10.17182/hepdata.26509

The polarization parameter in elastic π−p scattering has been measured, at the Berkeley 184-in. synchrocyclotron, with the use of a polarized proton target. At 318-, 337-, and 390-MeV incident pion kinetic energy, the angular range from 70° to 180° in the center-of-mass system was covered. At 229 MeV, polarization measurements were made in the angular range 150° to 180°. Phase-shift analyses, using these and other published data, were made at the two lowest energies.

Small-Angle pi- p Elastic Scattering Measurements

Apokin, V.D. ; Derevshchikov, A.A. ; Matulenko, Yu.A. ; et al.
Phys.Lett.B 56 (1975) 391-394, 1975.
Inspire Record 90800 DOI 10.17182/hepdata.27866

We have measured small angle elastic pion-proton scattering in 40 and 50 GeV c π − beams at Serpukhov. Analysis of the data in the Coulomb interference region yields a value for the ratio of the real to the imaginary part of the strong amplitude, ϱ (0)=−0.074 ± 0.033 at 40 GeV/ c and ϱ (0)=−0.006 ±0.026 at 50 GeV/ c

We have measured elastic pion-proton scattering in a 50 GeV/ c π − beam at the 76 GeV proton synchrotron in Serpukhov. Data are presented for four-momenta transfer squared in the range 0.03 < t < 0.4 (GeV/ c ) 2 .

Interactions of pi+ Mesons with Protons at 2.08 BeVc

James, Frederick E. ; Kraybill, Henry L. ;
Phys.Rev. 142 (1966) 896-912, 1966.
Inspire Record 50875 DOI 10.17182/hepdata.26717

Interactions of 2.08−BeVc positive pions with protons have been studied using the 20-in. hydrogen bubble chamber and the alternating gradient synchrotron at Brookhaven National Laboratory. Using 3000 elastic and 8000 inelastic events, the partial cross sections for elastic scattering and for meson production have been measured. The ρ+, ρ0, ω0, and η0 resonances are produced strongly and emerge predominantly in the forward direction in the center-of-mass system, suggesting a peripheral mechanism for their production. The possibility of explaining these reactions by specific particle-exchange models is investigated. More than 75% of the ρ0, ω0, and η0 are produced with the N33* (1238) isobar. The N* (1688) is produced in about one-third of the π+π+N final states. Cross sections for production of ρ+p, π+pω, N33*ω, π+pη, N33*η, π+pρ0, N33*ρ0, N15*π+, and N33*π0, are given. A1, B, φ, and X mesons are not observed.
