Total cross-section measurement at the isr

Amendolia, S.R. ; Bellettini, G. ; Braccini, P.L. ; et al.
Nuovo Cim.A 17 (1973) 735-755, 1973.
Inspire Record 87700 DOI 10.17182/hepdata.37766

We present the first results of an experiment at the CERN intersecting storage rings, which measures the total cross-section in proton-proton collisions. The equivalent laboratory momenta are 291, 496, 1068 and 1480 GeV/c. We have made a direct measurement of αT as the ratio between the total interaction rate and the machine luminosity. The present paper gives a detailed description of the experimental apparatus and of the analysis procedure. We find that αT increases by about 10% in the energy region studied.

Two-prong fitted channels at 11.7 gev/c

Evans, D. ; Neat, K. ; Caso, C. ; et al.
Nuovo Cim.A 16 (1973) 299-314, 1973.
Inspire Record 87004 DOI 10.17182/hepdata.37784

A sample of 43000 two-prong events obtained at a momomentum of 11.7 GeV/c is used to determine the cross-sections of the fitted channels, and to study the reaction π+p→π+pπ0. We investigate in particular the quasi-two-body channels π0Δ++ and ρ+p.

Polarization in pi+ p ---> k+ sigma+ backward scattering at 3.5 gev/c

Bradamante, F. ; Conetti, S. ; Daum, C. ; et al.
Phys.Lett.B 44 (1973) 202-206, 1973.
Inspire Record 84846 DOI 10.17182/hepdata.28109

In a counter and wire spark chamber experiment with a polarized target, backward kaons were detected, and the Σ + 's identified by a missing-mass technique. An average polarization of −0.08 ± 0.05 was found for −0.2 < u < 0.1 GeV 2 .

Production of high transverse momentum particles in p p collisions in the central region at the CERN ISR

The British-Scandinavian ISR collaboration Alper, B. ; Boggild, H. ; Jarlskog, G. ; et al.
Phys.Lett.B 44 (1973) 521-526, 1973.
Inspire Record 85256 DOI 10.17182/hepdata.28095

The inclusive production al all charged particles of transverse momentum p T between 1.5 and 4.4 GeV/ c at centre of mass angles 90° and 59.4° from p-p-collisions with √ s = 44 and 53 GeV has been measured. No strong energy dependence is observed for these transverse momenta.

Target asymmetry for neutral pi meson photoproduction on polarized protons at 4 GeV in the forward direction

Bienlein, H. ; Braunschweig, W. ; Dinter, H. ; et al.
Phys.Lett.B 46 (1973) 131-134, 1973.
Inspire Record 84690 DOI 10.17182/hepdata.28065

The asymmetry A = (σ + −σ − ) (σ + +σ − ) of the reaction γ p↑↓ → π 0 p was measured at the Deutsches Elektronen Synchrotron DESY, Hamburg at a mean photon energy of 4.0 GeV in the four-momentum transfer range 0.2 (GeV/ c ) 2 ⩽ −t ⩽ 1.1 (GeV/ c ) 2 in steps of approximately 0.08 (GeV/ c ) 2 . The π 0 -meson and the proton were detected in coincidence. The asymmetry is compatible with zero in the t -range 0.2 (GeV/ c ) 2 ⩽ − t ⩽ 0.4 (GeV/ c ) 2 and negative in the t -range ⩾ 0.5 (GeV/ c ) 2 .

A comparison of the production of k*(890) in k+ p and k- p interactions

Carney, J.N. ; Colley, D.C. ; Jobes, M. ; et al.
Phys.Lett.B 42 (1972) 124-128, 1972.
Inspire Record 85042 DOI 10.17182/hepdata.28222

Results are presented on an analysis of the reaction K + p → K ∗+ (890) p at 16 GeV/ c and compared with data at lower incident momenta and with corresponding results for the reaction K − p → K ∗− (890) p. It is found for both reactions that the energy dependence of the cross section exhibits a simple ( p − n lab behaviour.
