Additional data in the reaction pi+ p ---> sigma+ k+ at 1.28 and 1.41 gev/c and a test of charge independence in the center-of-mass energy range 1.820 to 2.090 gev

Data at two additional π+ momenta (1.28 and 1.41 GeVc) in the reaction π+p→Σ+K+ are presented. Charge independence is tested over the c.m. energy range 1.820 to 2.090 GeV; we used our data for the Σ+K+ channel and published data for the π−p→Σ0K0 and Σ−K+ channels.

Further results on small angle elastic proton proton scattering at very high energies

Holder, M. ; Radermacher, E. ; Staude, A. ; et al.
Phys.Lett.B 36 (1971) 400-402, 1971.
Inspire Record 69148 DOI 10.17182/hepdata.28407

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.

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

Phys.Lett.B 36 (1971) 504-508, 1971.
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.

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.

Small momentum transfer pi+ production with linearly polarized photons

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.

Momentum transfer dependence of nucleon resonance production in proton proton collisions at 24 gev/c

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.

Inspire Record 69081 DOI 10.17182/hepdata.28375

Elastic scattering of linearly polarized photons on protons has been measured between 3.2 and 3.7 GeV for four-momentum transfers ranging from −0.1 to −0.7 (GeV/ c ) 2 . The observed cross section asymmetry in this range is consistent with zero within ±0.05.

Inspire Record 69109 DOI 10.17182/hepdata.28392

Measurements of multiple particle production at ADONE, the Frascati e + e − storage ring, have been carried out at C.M. energies 1.4 GeV to 2.4 GeV. The hadronic nature of the observed particles is discussed and a lower limit of 30 nbarn set for the total multiparticle cross section.
