Abstract

Integral cross sections for the elastic scattering of π⁺ by protons into angles greater than 20° or 30° (lab) have been measured by the beam-attenuation technique over the energy range of 45–126MeV. The measurements are aimed at providing independent checks on the absolute normalization of differential cross sections, where discrepancies exist between different data sets. Comparisons with predictions made with existing phase shifts show very good agreement with the dispersion-relation constrained phase shifts of the Karlsruhe group.

Low energy (Tπ<300 MeV) pion nucleon interactions and the problem of the σ-term (strange content of the nucleon)
1996, Progress in Particle and Nuclear Physics
Recent experimental results of pion nucleon interactions below pion energies of about 300 MeV are reviewed. The Karlsruhe-Helsinki phases from the dispersion analysis of 1979 (KH80) are used for comparison as a ‘standard’ because they respect Mandelstam analyticity and unitary and, hence, allow a unique extrapolation to the threshold and to the Cheng-Dashen point which is crucial for a determination of the σ-term of pion nucleon scattering.
