Fluctuations in Large Angle $\pi^\pm p$ Elastic Scattering

Jenkins, K.A. ; Price, L.E. ; Klem, R. ; et al.

Phys.Rev.Lett. 40 (1978) 429, 1978.

Inspire Record 6210 DOI 10.17182/hepdata.76245

Large-angle π±p elastic-scattering cross sections, measured between 2 and 9 GeV/c in fine intervals of incident momentum and scattering angle, are used to search for cross-section fluctuations occurring for small changes in the center-of-mass energy as suggested by Ericson and Mayer-Kuckuck and by Frautschi. Significant fluctuations are observed.

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.
