Recoil-proton polarization in neutral-pion photoproduction and in proton Compton scattering

Deutsch, M. ; Golub, L. ; Kijewski, P. ; et al.
Phys.Rev.Lett. 29 (1972) 1752-1755, 1972.
Inspire Record 84562 DOI 10.17182/hepdata.21426

We have measured the polarization of the recoil proton in the reactions γp→π0p and γp→γp for incident photon energies between 3 and 7 GeV, and t values from -0.2 to -0.65 GeV2. The polarization in neutral-pion production varies from 0 to -1 over this range. Contrary to expectation, it does not agree completely with the polarized-target asymmetry.

Real Part of the Proton-Proton Forward Scattering Amplitude from 50-GeV to 400-GeV.

Bartenev, V. ; Carrigan, Richard A. ; Chiang, I-Hung ; et al.
Phys.Rev.Lett. 31 (1973) 1367-1370, 1973.
Inspire Record 81733 DOI 10.17182/hepdata.21379

From measurements of proton-proton elastic scattering at very small momentum transfers where the nuclear and Coulomb amplitudes interfere, we have deduced values of ρ, the ratio of the real to the imaginary forward nuclear amplitude, for energies from 50 to 400 GeV. We find that ρ increases from -0.157 ± 0.012 at 51.5 GeV to +0.039 ± 0.012 at 393 GeV, crossing zero at 280 ± 60 GeV.

Pi0 photoproduction from neutrons

Osborne, A.M. ; Brownam, A. ; Hanson, K. ; et al.
Phys.Rev.Lett. 29 (1972) 1621-1624, 1972.
Inspire Record 84571 DOI 10.17182/hepdata.21431

We have measured the ratio of the cross section for γ+n→π0+n to the cross section for γ+p→π0+p at 4.7 and 8.2 GeV. The measurements were made by detecting the recoil nucleons in coincidence with the decay γ rays of the π0's produced from a deuterium target. At 4.7 GeV the cross-section ratio, R≡σ(γ+n→π0+n)σ(γ+p→π0+p), is less than 1.0 at low t, with an indication of a dip at about t=−0.7(GeVc)2, and rises to 1.0 at high t. The ratios at the higher energy have less structure and are uniformly closer to 1.0.

Observations on anti-p d annihilations at rest into two pions

Gray, L. ; Papadopoulou, T. ; Simopoulou, E. ; et al.
Phys.Rev.Lett. 30 (1973) 1091-1094, 1973.
Inspire Record 84510 DOI 10.17182/hepdata.21409

The ratio (p¯d→π−π0ps)(p¯d→π−π+n) at rest, with spectator momenta ≲300 MeVc, has been measured and found to be 0.68 ± 0.07. This implies that (75 ± 8)% of the annihilations in deuterium into two pions come from odd N¯N orbital angular momenta, in disagreement with the S-state-dominance hypothesis. It has also been observed that the p¯d→π−π0ps production rate depends on the spectator momentum, which suggests energy-sensitive N¯N phenomena near threshold.

Measurement of the Slope of the Diffraction Peak for Elastic pp Scattering from 8-GeV to 400-GeV.

Bartenev, V. ; Kuznetsov, A. ; Morozov, B. ; et al.
Phys.Rev.Lett. 31 (1973) 1088-1091, 1973.
Inspire Record 81722 DOI 10.17182/hepdata.21381

The slope b(s) of the forward diffraction peak of p−p elastic scattering has been measured in the momentum-transfer-squared range 0.005≲|t|≲0.09 (GeV/c)2 and at incident proton energies from 8 to 400 GeV. We find that b(s) increases with s, and in the interval 100≲s≲750 (GeV)2 it can be fitted by the form b(s)=b0+2α′lns with b0=8.23±0.27, α′=0.278±0.024 (GeV/c)−2.
