Properties of the inelastic k+ p reactions between 1.2 and 1.7 gev/c

Berthon, A. ; Montanet, L. ; Paul, E. ; et al.
Nucl.Phys.B 63 (1973) 54-92, 1973.
Inspire Record 83879 DOI 10.17182/hepdata.32479

The observation of 70 000 K 0 p π + events produced with K + incident momenta of 1.21, 1.29, 1.38 and 1.69 GeV/ c allows a detailed description of the production and decay of the Δ(1236) and K ∗ (892) resonances which dominate the K 0 p π + final state. No striking variations with energy are observed. The associated production of Δ and K ∗ near threshold shows striking similarities with the same production at higher energy.

New Data on K- p --> K- p and anti-K0 n and a Partial Wave Analysis Between 1840-MeV and 2234-MeV Center-of-Mass Energy

Hemingway, R.J. ; Eades, J. ; Harmsen, D.M. ; et al.

Inspire Record 98477 DOI 10.17182/hepdata.32035

The angular distributions of the reactions K - p → K - p and K - p → K K 0 n have been measured at 23 incident K - momenta between 1.136 and 1.798 ifGeV/c using the bubble chamber technique. These data, together with other published data on the same reactions, including K - p polarisations, K̄N total cross sections, and measurements of Re ƒ(0)/ Im ƒ(0) , have been analysed in terms of partial-wave amplitudes. Resonance behaviour is confirmed for the P 03 partial wave at 1890 MeV. The resonance parameters of the F 15 (1915), F 17 (2030) and G 07 (2100) have been redetermined. No evidence has been found for new resonances coupling significantly to K K N in the energy region explored.

Study of the reaction pi- p ---> pi0 n between 1.0 and 2.4 gev/c

Nelson, Jerry E. ; Chaffee, R.B. ; Dahl, O.I. ; et al.
Phys.Lett.B 47 (1973) 281-284, 1973.
Inspire Record 95427 DOI 10.17182/hepdata.38182

The differential cross section for the reaction π − p→n π ° has been measured with high statistics at six incident beam momenta between 1.0 and 2.4 GeV/ c . The results are compared with predictions of recent phase shift analyses and forward dispersion relations.

Differential Cross-Sections for anti-Proton-Proton Elastic Scattering Between 0.69-GeV/c and 2.43-GeV/c

Eisenhandler, E. ; Gibson, W.R. ; Hojvat, C. ; et al.
Nucl.Phys.B 113 (1976) 1-33, 1976.
Inspire Record 109426 DOI 10.17182/hepdata.8439

Measurements have been made of the differential cross section for p p elastic scattering over a c.m. angular range −0.95 ⩽ cos θ ∗ ⩽ 0.93 at 21 incident antiproton momenta between 0.69 GeV/ c and 2.43 GeV/ c (c.m. energy 1.96–2.58 GeV). About 10 5 events were obtained at each momentum. The results are discussed primarily in terms of the formation of s -channel resonances in the T and U mass regions, and within the context of the optical model of Frahn and Venter.
