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 .

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.

Measurement of the total proton proton cross-section at the ISR

Amendolia, S.R. ; Bellettini, G. ; Braccini, P.L. ; et al.
Phys.Lett.B 44 (1973) 119-124, 1973.
Inspire Record 83730 DOI 10.17182/hepdata.28114

We present the first results of a measurement of the total cross-section σ T in proton-proton collisions at equivalent laboratory momenta between 291 and 1480 GeV/ c at the CERN Intersecting Storage Rings (ISR). The method is based on the measurement of the ratio of the total interaction rate and the machine luminosity. The data show an increase of about 10% in σ T in this energy interval.

Measurement of the spin rotation parameter r in proton proton elastic scattering at 6 and 16 gev/c

Deregel, J. ; Bystricky, J. ; Cozzika, G. ; et al.
Phys.Lett.B 43 (1973) 338-340, 1973.
Inspire Record 84912 DOI 10.17182/hepdata.28132

The spin rotation parameter R in elastic proton-proton scattering has been determined at incident momenta 6 and 16 GeV/ c in the interval from t = −0.18 (GeV/ c ) 2 to −0.54 (GeV/ c ) 2 . R pp at 16 GeV/ c is close to the val obtained for R in π − p elastic scattering at the same incident momentum. Equality of R pp ( s , t ) and R π p ( s , t ) is expected if Pomeron exchange dominates and if factorization holds. The t -dependence of R at 16 GeV/ c is consistent with weak helicity flip.

The charge exchange anti-p p ---> anti-n n at 5.0 and 7.76 gev/c near the forward direction

Lee, J.G. ; Harckham, A. ; Letheren, M. ; et al.
Nucl.Phys.B 52 (1973) 292-300, 1973.
Inspire Record 84235 DOI 10.17182/hepdata.32683

The differential cross section for the charge exchange p p → n n has been measured with high statistics at 7.76 GeV/ c and at 5.0 GeV/ c . The 7.76 GeV/ c data show a very narrow [ Δt ⪅ 0.01 (GeV/ c ) 2 ] forward peak superposed on a slow exponential fall-off.

Single photoproduction of neutral pi mesons on deuterium in the forward direction at 4 gev

Inspire Record 84302 DOI 10.17182/hepdata.32703

The ratio R = (d σ /d t )( γ d → ( π 0 n)p)/(d σ /d t )( γ d → ( π 0 p)n), was measured at the Deutsches Elektronen-Synchrotron DESY, Hamburg at a mean photon energy of 4.0 GeV in the four-momentum transfer range between t = − 0.2 (GeV/ c ) 2 and t = − 1.2 (GeV/ c ) 2 in steps of approximately 0.08 (GeV/ c ) 2 . The ratio R is less than 1 up to t = − 0.9 (GeV/ c ) 2 and shows a broad minimum around t = − 0.6 (GeV/ c ) 2 . Corrections for nuclear effects in the deuterium were not applied but are shown to be small.

High-energy proton scattering on nuclei

Klovning, A. ; Kofoed-Hansen, O. ; Schluepmann, K. ;
Nucl.Phys.B 54 (1973) 29-41, 1973.
Inspire Record 84178 DOI 10.17182/hepdata.32651

We have studied high-energy proton scattering on Be, C, Cu and Pb targets using a single-arm spectrometer. The projectile momenta were 19 and 24 GeV/ c , the square of the four-momentum transfer varied from t = 0.1 to t = 4.4 GeV 2 . We have recorded momentum distributions of scattered protons in the high-momentum range. An application of multiple-scattering theory yielded agreement of calculation and experimental results to within a ± 30% uncertainty of the former.

The differential cross section of the reaction γ p → π 0 p has been measured at the Deutsches Elektronen Synchrotron DESY, Hamburg, at a mean photon energy of 4.0 GeV in the four-momentum transfer range between t = −0.2 (GeV/ c ) 2 and t = −1,2 (GeV/ c ) 2 in steps of approximately 0.08 (GeV/ c ) 2 . The experiment was carried out in connection with the measurements of the photoproduction of π 0 mesons on deuterium, which were described in the preceding article. In the present paper the contributions arising from background reactions are discussed in more detail.
