The Real Part of the Forward Scattering Amplitude in pi+- p Elastic Scattering Below 2-GeV/c

Baillon, P. ; Bricman, C. ; Eberhard, P. ; et al.
Phys.Lett.B 50 (1974) 387-390, 1974.
Inspire Record 89683 DOI 10.17182/hepdata.27947

The differential cross section for π ± p elastic scattering below 2 GeV/ c has been measured at small forward pion angles by an electronics experiment. The interference effects observed between the Coulomb and the nuclear interaction have been used to determine the magnitude and sign of the real parts of the π ± p forward scattering amplitude. The latter are compared to the values predicted by the dispersion relations.

Neutron-Proton Forward Angle Elastic Cross-Sections at 790-MeV

Carlini, R. ; Dieterle, B. ; Donahue, J. ; et al.
Phys.Rev.Lett. 41 (1978) 1341-1344, 1978.
Inspire Record 136558 DOI 10.17182/hepdata.20861

High-statistics measurements of the absolute differential cross section for n−p scattering have been made over neutron c.m.-system scattering angles 9.5°<θ*<64.5°. The statistical error is 1.7 to 3.3% for 2°-wide angular bins, and the systematic error is 2.7 to 3.3%. The cross section is fitted by dσdΩ*=A exp(bt), with A=10.27±0.36 mb/sr, b=5.00±0.05, and 0.01<−t<0.39 (GeV/c)2. For the ratio of the real to the imaginary part of the forward-scattering amplitude we obtained αn>~−0.43±0.04, consistent with other less precise determinations of αn.

Inspire Record 140694 DOI 10.17182/hepdata.50217

At the Bonn 2.5 GeV electron synchrotron we have measured the differential cross section of the reaction γp→π0p at a pion CM angle of 170° and at photon energiesKγ between 0.6 and 1.8 GeV. In comparison to previous measurements the accuracy of the data was improved substantially. For the first time in neutral pion photoproduction a cusp structure at the η-threshold has been confirmed [1].

MEASUREMENT OF THE ANTI-P P ---> ANTI-N N DIFFERENTIAL CROSS-SECTIONS AT LOW MOMENTA AND CONFIRMATION OF THE FORWARD DIP

Phys.Rev.Lett. 53 (1984) 885-888, 1984.
Inspire Record 207326 DOI 10.17182/hepdata.20405

The differential cross sections of the reaction p―p→n―n were measured at 390, 490, 590, 690, and 780 MeV/c. The existence of the theoretically predicted forward dip is confirmed. The results are compared with the predictions of various N―N potential models.

OBSERVATION OF AN ENHANCEMENT IN ANTI-P P ---> PI+ PI- AND ANTI-P P ---> K+ K- CROSS-SECTIONS AT ANTI-P MOMENTUM OF APPROXIMATELY 500-MEV/C

Tanimori, T. ; Fujii, T. ; Kageyama, T. ; et al.
Phys.Rev.Lett. 55 (1985) 1835-1838, 1985.
Inspire Record 221965 DOI 10.17182/hepdata.20293

The reactions p¯p→π+π− and K+K− have been studied at 390, 490, 590, 690, and 780 MeV/c. An enhancement of about 150 μb has been observed in the cross sections of both reactions at the same beam momentum of 490 MeV/c. If this structure is interpreted as a meson resonance, it has a mass of 1940 ± 20 MeV and a width of less than 40 MeV.
