Results are reported on the Δ ++ ϱ 0 and the Δ ++ ω 0 final states obtained from a 4 event/μb exposure of the Argonne National Laboratory 30 inch hydrogen bubble chamber to a π + beam at 5.45 GeV/ c . Data are presented on cross sections, differential cross sections, spin density matrix elements and differential cross-sections weighted by density matrix elements. Certain features of the data relevant to various Regge models are noted and the data is compared to a π -B exchange degenerate Regge model due to Abrams and Maor.

A Study of rho and Omega Production in pi+ p Interactions at 15.7-GeV/c

Ferguson, Merl McDonald, Jr. ;

Phys.Rev.D 36 (1987) 1961, 1987.

Inspire Record 210652 DOI 10.17182/hepdata.12775

We report the results of a study of ρ and ω production in π+p interactions at 15.7 GeV/c. The SLAC hybrid bubble-chamber facility was used to study reactions in which neutral particles are produced. Three tantalum plates inside the 40-in. bubble chamber and a large array of lead glass downstream of the chamber provided photon detection over a large solid angle. Final states with two neutral particles have been isolated with kinematic fits in which neutral pions were reconstructed in the plates and lead glass. Data from an earlier untriggered π+p bubble-chamber experiment at 15 GeV/c were used to obtain samples of events in channels which did not trigger the hybrid system. Cross sections for ρ and ω production are given for several exclusive final states. Relative ρ and ω production rates are studied. The ratio of nondiffractive ω to ρ0 production is measured to be ω/ρ0=0.44±0.07. We estimate the inclusive ω cross section to be 1.9±0.3 mb. The results are compared to the Lund model of low-pT hadronic reactions.

Amplitude Analyses of the Reactions pi+ p --> (rho0, omega) Delta++ at 7.1-GeV/c

Owens, J.F. ; Eisner, R.L. ; Chung, S.U. ; et al.

Nucl.Phys.B 112 (1976) 514-544, 1976.

Inspire Record 3423 DOI 10.17182/hepdata.35710

New data are presented, in the form of statistical tensors, for the reactions π + p → ( ϱ 0 , ω ) Δ ++ at 7.1 GeV/ c . Using these data, two types of model-dependent amplitude analyses have been performed. Both analyses, though based on different sets of assumptions, yield results which are in agreement with each other. The structure observed in the magnitudes and phases of the extracted amplitudes is consistent with that expected on the basis of currently accepted phenomenological ideas.
