Reaction pi+ p ---> rho+ p at 2.67 gev/c - a study of isoscalar exchanges

Michael, W. ; Gidal, G. ;
Phys.Rev.Lett. 28 (1972) 1475-1479, 1972.
Inspire Record 75483 DOI 10.17182/hepdata.21443

Results are presented of a study of the reaction π+p→ρ+p at 2.67 GeV/c incident π+ momentum. The contributions due to given spin-parity exchanges are isolated; and, by combining these results with those of a similar π− experiment, the It=0 component of each series is separated. The ω (I=0, JPG=1−−) exchange contribution shows a pronounced dip at −t=0.4 (GeV/c)2. Evidence is presented for the exchange of a state of minimum quantum numbers, H (I=0, JPG=1+−).

A SPARK CHAMBER MEASUREMENT OF THE REACTIONS PI+- P ---> RHO+- P AT 15-GEV/C

Pratt, J.C. ; Kaune, W.T. ; Lakin, W.L. ; et al.
Phys.Lett.B 41 (1972) 383, 1972.
Inspire Record 73430 DOI 10.17182/hepdata.28236

A new method, using spark chambers, for the study of the reactions π ± + p → ϱ ± + p is described. The charged pion and both γ rays from the π ± decay are detected. Differential and integrated cross sections σ π + =50 ± 9 μ b, σ π − =47 ± 9 μ b) for 0.0 ⩽| t |⩽1. (GeV/ c ) 2 and a laboratory momentum ( p Lab ) of 15 GeV/c are presented. The momentum dependence of σ γ ± is well fitted from 2.7 to 16 GeV/c by σ = K p Lab − with n γ + = 1.80 ± 0.80 and n γ − = 1.87 ± 0.15.

Nuovo Cim.A 16 (1973) 299-314, 1973.
Inspire Record 87004 DOI 10.17182/hepdata.37784

A sample of 43000 two-prong events obtained at a momomentum of 11.7 GeV/c is used to determine the cross-sections of the fitted channels, and to study the reaction π+p→π+pπ0. We investigate in particular the quasi-two-body channels π0Δ++ and ρ+p.

An Investigation of rho Meson Production in pi p Interactions at 3.9-GeV/c

Haber, B. ; Hodous, M.F. ; Hulsizer, R.I. ; et al.
Phys.Rev.D 10 (1974) 1387, 1974.
Inspire Record 819 DOI 10.17182/hepdata.25008

We have investigated the ρ-meson production mechanism in the three reactions π±p→ρ±p and π−p→ρ0n at 3.9 GeV/c (s=8.2 GeV2) using the prism-plot technique. Differential cross sections at all momentum transfers are presented. A significant backward peak has been found in all three reactions. The differential cross sections for these backward peaks are given and are compared with the equivalent pion elastic and charge-exchange cross sections in the backward direction. Using a linear combination of the three differential cross sections we have isolated the I=0 exchange contribution in the forward direction. This differential cross section has a zero at −t=0.45 (GeV/c)2 and is fitted by the dual absorptive model of Harari with an interaction radius of ∼ 1.2 F. The total I=0 cross section is calculated and compared with similarly determined cross sections at higher momenta. An analysis of the properties of the other possible spin-parity exchanges is also presented.

Meson Production by Delta Exchange in pi- p Interactions at 4-GeV/c

Scharre, D.L. ; Chapman, J.W. ; Ely, R.P. ; et al.
Phys.Rev.D 17 (1978) 2853, 1978.
Inspire Record 121388 DOI 10.17182/hepdata.24432

A streamer-chamber spectrometer is triggered by fast forward protons from 4-GeV/c π−p interactions at the Bevatron. Meson-resonance production in the backward, Iu=32 exchange reactions π−p→pM− are studied, where M− refers to π−, ρ−, A1−, A2−, and B−. Elastic scattering and ρ− production are observed and discussed in detail. No backward A1−, A2−, or B− production is observed at the level of approximately 5 βb.
