Single-pion production in k+ p interactions at 4.6 gev/c

Fu, C. ; Macnaughton, J. ; Trilling, G.H. ;
Nucl.Phys.B 28 (1971) 528-540, 1971.
Inspire Record 68682 DOI 10.17182/hepdata.33570

A study of K + p interactions at 4.6 GeV/ c leading to single-pion production is presented. Cross sections for the final states KΔ, K ∗ (891)p, K ∗ (1420)p are given. Comparison of the results of this study with published K − p and K − n data at the same momentum indicates that corresponding K − cross sections are significantly smaller, but other features such as momentum transfer distributions and density matrix elements are very similar.

This work extends our previous investigations at the CERN Intersecting Storage Rings, with improved statistics at three different energies, wider angular range and a better control over systematic errors. Values for the (diffraction) shape parameter b are given.

The absolute luminosity of the CERN Intersecting Storage Rings has been determined by the Van der Meer method. Combining the measurement with small angle proton-proton elastic events, we find σ elastic = (6.8±0.6)mb.

Proton proton total cross-sections between 179 and 555 mev

Schwaller, P. ; Pepin, M. ; Measday, David F. ; et al.
Phys.Lett.B 35 (1971) 243-246, 1971.
Inspire Record 69250 DOI 10.17182/hepdata.28479

Proton-proton total cross-sections have been measured at nine different energies between 179 and 555 MeV (607 and 1162 MeV/ c ) with a typical accuracy of 0.9%. The accuracy is limited by a poor knowledge of the Coulomb-nuclear interference region in elastic scattering.

Small momentum transfer pi+ production with linearly polarized photons

Burfeindt, H. ; Buschhorn, G. ; Geweniger, C. ; et al.
Phys.Lett.B 33 (1970) 509-510, 1970.
Inspire Record 69381 DOI 10.17182/hepdata.28537

Previous measurements of the cross section asymmetry for single π + production on protons with linearly polarized photons of 3.4 GeV have been extended to momentum transfers within the forward peak, i.e. − = 0.0026, 0.006 and 0.01 (GeV/ c ) 2 . The results are in good agreement with pion exchange models.

Inspire Record 69310 DOI 10.17182/hepdata.28714

Nucleon resonance production in the two-body reaction p + p → p + N ∗ has been studied at 24 GeV/ c incident momentum for angles from 12 to 117 mrad by measuring proton momentum spectra from the elastic peak down to a momentum corresponding to a missing mass of about 2.6 GeV.

Measurements of small angle proton proton elastic scattering at the cern intersecting storage rings

Inspire Record 69145 DOI 10.17182/hepdata.28393

Proton-proton elastic scattering has been measured over the angular range 7 to 16 mrad at centre-of-mass energies of 31, 45 and 53 GeV using the CERN Intersecting Storage Rings. The results indicate that the diffraction peak has continued to shrink with increasing energy, but not as fast as suggested by the results at lower energies.

Observation of small angle proton proton elastic scattering at 30 gev and 45 gev center-of-mass energies

Holder, M. ; Radermacher, E. ; Staude, A. ; et al.
Phys.Lett.B 35 (1971) 355-360, 1971.
Inspire Record 69228 DOI 10.17182/hepdata.5781

Small angle elastic scattering events have been observed at the CERN Intersecting Storage Rings. Directions of both particles as well as the collision vertex are reconstructed with the help of four sets of spark chambers, two for each of the two arms. The elastic nature of the events is demonstrated by a collinearity requirement. We find values for the (diffraction) slope parameter in disagreement with the simple linear extrapolation of lower energy (Surpukov) data.
