Pi+ p elastic scattering data between 1820- and 2090-mev center-of-mass energy

Kalmus, G.E. ; Michael, W. ; Birge, R.W. ; et al.
Phys.Rev.D 4 (1971) 676-683, 1971.
Inspire Record 67772 DOI 10.17182/hepdata.3686

Total and differential elastic cross-section data are presented at eight incident π+ momenta: 1.28, 1.34, 1.40, 1.43, 1.55, 1.68, 1.77, and 1.84 GeVc. These data were obtained from a hydrogen-bubble-chamber exposure at the Bevatron, and contain more than 65 000 events. This represents more than 1½ times the world's data hitherto available in this energy region.

Photoproduction of k+ lambda and k+ sigma0 in hydrogen between 1.19 and 1.68 gev

Goeing, H. ; Schorsch, W. ; Tietge, J. ; et al.
Nucl.Phys.B 26 (1971) 121-133, 1971.
Inspire Record 68818 DOI 10.17182/hepdata.33752

New measurements on the reactionsγp→K + Λ and γp→K + Σ o have been performed at the DESY synchrotron at c.m. angles around 90° and photon lab. energies from 1.19 to 1.68 GeV. The produced K + mesons were analyzed by a magnet spectrometer, two thresholdCˇerenkov counters and a time-of-flight measurement. The obtained differential cross-section data show a smooth energy behaviour for the K + Λ production whereas for theK + Σ o production the data trace out a bump at a c.m. energy W ≈ 1.9GeV.

Resonance production in k- neutron interactions at k- momenta of 1.45 and 1.65 gev/c

Colley, D.C. ; Cox, G.F. ; Eastwood, D. ; et al.
Nucl.Phys.B 31 (1971) 61-85, 1971.
Inspire Record 68588 DOI 10.17182/hepdata.33257

Results are reported on K − -neutron interactions at c.m. energies near 2 GeV. The interactions are dominated by strong production of hyperon resonances, particularly Σ(1385), Λ(1405) and Λ(1520). Production cross sections and angular distributions are given for the Σ(1385), Λ(1405) and Λ(1520) and branching fractions to decay modes observed in the experiment are given for Σ(1385) and Λ(1520). The strong energy dependence of some features of the data suggests that s -channel effects are dominant.

Coincidence measurements of single pi+ electroproduction

Phys.Rev.Lett. 26 (1971) 987-991, 1971.
Inspire Record 69020 DOI 10.17182/hepdata.21506

We have studied the reaction e−+p→e−+π++n by detecting the final electron and pion in coincidence. Data are presented in the region of virtual photon mass squared from -0.18 to -1.2 GeV2, and virtual photoproduction center-of-mass energy and angle from 1.85 to 2.50 GeV and 0 to 20°, respectively.

Electromagnetic proton form-factors at squared four momentum transfers between 1-GeV/c**2 and 3-GeV/c**2

Bartel, W. ; Busser, F.W. ; Dix, W.R. ; et al.
Phys.Lett.B 33 (1970) 245-248, 1970.
Inspire Record 63047 DOI 10.17182/hepdata.45284

Electron-proton elastic scattering cross sections have been measured at four-momentum transfers between 1.0 and 3.0 (GeV/ c ) 2 and at electron scattering angles between 10° and 20° and at about 86° in the laboratory. The proton electromagnetic form factors G E and G M were determined. The results indicate that G E ( q 2 ) decreases faster with increasing q 2 than G M ( q 2 ).

Study of k- pi- scattering using the reaction k- d ---> k- pi- p p(s)

Phys.Lett.B 32 (1970) 409-412, 1970.
Inspire Record 63111 DOI 10.17182/hepdata.28719

Approximately 700 events of the reaction K − d → K − π − pp s produced by 5.5 GeV/ c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

Chew-Low extrapolation is used for evaluation of the K- P elastic cross section.


Photoproduction of neutral pions on hydrogen at photon energies between 200 and 440 mev

Fischer, G. ; Fischer, H. ; Von Holtey, G. ; et al.
Nucl.Phys.B 16 (1970) 93-101, 1970.
Inspire Record 62733 DOI 10.17182/hepdata.16659

Differential cross sections for neutral-pion photoproduction on hydrogen in the region of the first resonance have been measured by two independent experiments detecting the recoil protons. The results of both measurements have been combined into one set of cross sections covering the photon energy range from 200 to 440 MeV at pion c.m. angles between 50 and 160 degrees.

Inspire Record 63868 DOI 10.17182/hepdata.16698

The differential cross section has been measured for the reaction γ+p→K+ + Λ atk=1.3 GeV andCM angles between 6 ° and 90 ° and for the reaction γ+p→K+ + ∑0 atk=1.45 GeV andCM angles between 10 ° and 85 °. In addition 10 differential cross sections of the two reactions in the energy region betweenk=1.327 and 1.416 GeV and angles between θcm=11.2 ° and 62 ° have been obtained. The results are compared with Regge-cut-model fits by Meyer zu Hörste and Pfeil1 taking into account all availableK+ photoproduction data.
