Elastic Scattering of 3.5-BeV/c $\pi^-$ Mesons by Protons

THE study of elastic scattering at high energies in the region of the diffraction maximum has gained in interest recently in connection with the verifica- tion of the asymptotic expressions obtained by cal- culating the Regge-pole trajectories. We have in- vestigated the elastic scattering of 3. 5- Be VIc 7r- mesons by protons. The measurements were made with the aid of a liquid-hydrogen bubble chamber 25 em in diameter, placed in a 14 kOe magnetic field.

Differential cross sections for backward π− p → nπ0 from 2.6 to 8 GeV/c

Inspire Record 1389073 DOI 10.17182/hepdata.27860

We report differential cross sections for π − p → n π 0 in the backward hemisphere at incident momenta of 2.6, 3.5, 4.3, 6.0, and 8.0 GeV/c. We observe less pronounced structure than some previous measurements with a shallow dip displaced from that seen in π + p elastic scattering.

phi Meson Production in pi- p and K- p Interactions from 3-GeV/c to 6-GeV/c

Ayres, D.S. ; Diebold, R. ; Greene, A.F. ; et al.
Phys.Rev.Lett. 32 (1974) 1463, 1974.
Inspire Record 89228 DOI 10.17182/hepdata.51356

Cross sections and density-matrix elements for π−p→ϕn have been measured for - −t≲1.5 GeV2 at 3, 4, 5, and 6 GeV/c, using the Argonne effective-mass spectrometer to observe the decay ϕ(1019)→K+K−. This is the first observation of the reaction in this energy range. The remarkably flat differential cross section at 4 GeV/c and the strong energy dependence suggest a production mechanism not normally seen at these energies. Data on K−p→ϕΛ and K−p→ϕΣ0 from the same experiment are also presented.

MEASUREMENT OF POLARIZATION PARAMETERS FOR THE PI- P ---> PI0 N CHARGE EXCHANGE SCATTERING FROM 1965-MEV/C TO 4220-MEV/C

Nucl.Phys.B 294 (1987) 979-1000, 1987.
Inspire Record 255228 DOI 10.17182/hepdata.33402

Polarization parameters for the π − p → π 0 n charge exchange scattering have been measured at eight beam momenta between 1965 and 4220 MeV/ c using two different experimental set-ups. The angular range covered is −0.90 < cos θ π ∗ < 0.95 at the five momenta of 1965, 2168, 2360, 2566 and 2960 MeV/ c , where θ π ∗ is the emission angle of the π 0 meson in the c.m.s.. For three momenta of 2770, 3490 and 4220 MeV/ c , the measurements cover the forward angles of 0.1 < cos θ π ∗ < 1.0 . The results are compared with the predictions of π N partial wave analyses.

Measurement and analysis of the reaction pi+ p ---> eta0 delta++

New data for the reaction π+p→η0Δ++ are presented at 11 momenta between 1.28 and 2.67 GeV/c. Existing data at higher momenta are included in an analysis of the reaction in terms of A2 exchange. An effective trajectory parametrization of the data above 2 GeV/c is shown to describe adequately those data, although it yields an effective trajectory steeper than expected from ρ−A2 exchange degeneracy. An existing Regge-pole model is refitted to the data above 2 GeV/c with generally satisfactory results. Both the effective trajectory parametrization and the Regge model are extrapolated to the lower-momenta data and shown to give remarkably good agreement with the data. Evidence is presented against a dominant contribution to the lower-momenta data from s-channel resonances.

Study of four-prong events in pi+ p interactions at 3.5 gev/c

Ronat, E.E. ; Eisenberg, Y. ; Lyons, L. ; et al.
Nucl.Phys.B 38 (1972) 20-36, 1972.
Inspire Record 75333 DOI 10.17182/hepdata.32958

The non-strange four-prong events of π + p interactions at 3.5 GeV/ c are studied. Cross sections are calculated for all resonance productions in the channels π + p → p π + π + π − ( σ T = 3.18 ± 0.13 mb) and π + p → p π + π + π − π o ( σ T = 4.03 ± 0.16 mb). The dominant two body reactions Δ ++ ϱ o and Δ ++ ω o are investigated in detail, and production and decay distributions are presented as well as joint decay density matrix elements and joint correlation terms. The Δ ++ ϱ o reaction is compared to predictions of OPE with absorption and the Δ ++ ω o is compared to rho-exchange with sharp cutoff.
