Wide Angle Differential Cross-Sections for Elastic Proton Proton Scattering in the Region of Delta (1236) Production

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.

Phys.Rev.D 12 (1975) 1-5, 1975.

Inspire Record 103521 DOI 10.17182/hepdata.24866

Differential cross sections for p−p elastic scattering are presented with scattering angles in the center-of-mass system greater than 35° to 50°. The data were obtained at incident laboratory momenta 0.857, 1.091, 1.210, 1.374, 1.405, and 1.501 GeV/c. This spans the region of the onset of Δ(1236) production and where a possible spin-singlet D-wave resonance is indicated in an analysis of earlier data.

Differential Cross-Sections for K- p Elastic Scattering from 1.4-GeV/c to 1.9-GeV/c

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.

Phys.Rev.D 12 (1975) 6-14, 1975.

Inspire Record 103522 DOI 10.17182/hepdata.24826

We report here the results from an experiment to obtain differential cross sections for K−p elastic scattering in the laboratory momentum region from 1.4 to 1.9 GeV/c. These data span the region of a bump in the K−p total cross section at an energy of 2.05 GeV. Approximately 20000 elastic events were obtained at each of four momenta with an angular coverage of 0.9≥cosθc.m.≥−0.9. The data are intended to aid in phase-shift analyses of the resonances causing the bump in the total cross section and to study dip structures at constant values of the Mandelstam variables t and u.

Differential cross sections for elastic pi+ p scattering between 1.2 and 2.3 GeV/c

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.

Phys.Rev.D 10 (1974) 3556-3572, 1974.

Inspire Record 97248 DOI 10.17182/hepdata.238

Differential cross sections for π+p elastic scattering in the momentum region 1.2 to 2.3 GeV/c are presented for the center-of-mass angular range 0.9>cosθ>−0.9. Typically, 50 000 events were obtained at each of 16 momenta using magnetostrictive-readout wire spark chambers to detect the particles scattered from a liquid hydrogen target. The results are compared to those of the CERN-71 phase-shift analysis. The well-known dips at t≅−0.7 (GeV/c)2 and at u′=−0.2 (GeV/c)2 are observed. In addition, structure is seen at constant u′=−1.3 (GeV/c)2. The results of a pion attenuation study in iron are also presented.

DIFFERENTIAL CROSS-SECTIONS FOR K+ p ELASTIC SCATTERING FROM 0.865-GeV/c TO 2.125-GeV/c: DATA LISTING

Abe, K. ; Barnett, B.A. ; Goldman, J.H. ; et al.

Phys.Rev.D 11 (1975) 1719-1732, 1975.

Inspire Record 81409 DOI 10.17182/hepdata.4763

We report on an experiment to obtain differential cross sections for K+p elastic scattering in the vicinity of the possible exotic baryon, the Z1*(1900). The differential cross sections are based on typically 70 000 selected events in the angular region −0.9≤cosθc.m.≤0.9 at each of 22 momenta from 0.865 to 2.125 GeV/c. The data are intended for use in partial-wave analysis to search for the Z1*.

$pi^- -- p$ interactions at 905, 960, and 1100 {MeV}

Pickup, E. ; Robinson, D.K. ; Salant, E.O. ; et al.

Phys.Rev. 132 (1963) 1819-1830, 1963.

Inspire Record 44761 DOI 10.17182/hepdata.75462

Single-pion production in π−−p interactions has been studied at 905, 960, and 1100 MeV. Comparison with the isobar and one-pion-exchange (OPE) mechanisms of pion production shows that, below 1 BeV, pion production occurs primarily through the formation of an intermediate excited state of the nucleon (isobar), while at higher energies the influence of the ρ resonance in the ππ system becomes increasingly important. There is some evidence for an I=2 state in the events at the lower energies.

Inspire Record 114035 DOI 10.17182/hepdata.27668

Elastic scattering of 32.1 GeV/ c K + on protons has been measured in a bubble chamber experiment. Results are presented in the momentum transfer interval 0.06–1.40 GeV 2 and compared with data at different energies. An effective Regge trajectory is calculated using K + p elastic data from 10 to 175 GeV/ c .

In this paper we present tables of absolute differential cross sections of elastic pp scattering together with the values of the slope parameter B and the real-part parameter α, where B= d d t In dσ d t α= Re A(0) Im A(0) and A (0) is the amplitude of elastic pp scattering at t = 0. The cross-section data have been obtained at the Serpukhov accelerator from 8 to 70 GeV in the | t |-range 0.0007 − 0.12 (GeV/ c ) 2 .

Phys.Rev.D 3 (1971) 1-9, 1971.

Inspire Record 68275 DOI 10.17182/hepdata.23725

Proton-proton elastic differential cross sections have been measured for incident laboratory momenta of 600-1800 MeVc and c.m. angles of 5°-90°. The data span, in a single experiment, the intermediate energy region from isotropic differential cross sections at lower energies to the development of a clear diffraction peak at higher energies. Parameters for phenomenological formulations derived from the experimental results are presented.
