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

Amaldi, U. ; Biancastelli, R. ; Bosio, C. ; et al.
Phys.Lett.B 34 (1971) 435-438, 1971.
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.

Compton scattering of 3.5 gev polarized photons on protons

Buschhorn, G. ; Criegee, L. ; Franke, G. ; et al.
Phys.Lett.B 37 (1971) 211-212, 1971.
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.

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.

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

Amaldi, U. ; Biancastelli, R. ; Bosio, C. ; et al.
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.

Measurements of polarization in pi- p elastic scattering at large angles

We have made measurements of polarization in π−p elastic scattering, with emphasis over the backward region, at 1.60 to 2.28 GeVc. The results indicate the absence of u-channel dominance in the backward region, as was observed in the case of π+p scattering. Comparisons have been made with predictions of various phase-shift analyses which show that the agreement is generally very poor in the backward region.

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.
