We have measured differential cross sections for both π+p and π−p elastic scattering at incident-pion kinetic energies of 30, 50, 70, and 90 MeV in the center-of-mass angular range between 50° and 150°. The experiment detected pions scattered from a liquid-hydrogen target with multiwire proportional chambers and scintillation-counter range telescopes. The relative accuracy of each angular distribution is better than 5%, while the absolute cross sections have uncertainties of 4% to 25%. Our results for the absolute cross section for π+p scattering at 30 and 90 MeV are inconsistent with previous measurements. Our π−p measurements comprise the first extensive set of precision differential cross sections below 90 MeV.

Soft $\pi^- p$ and $p p$ Elastic Scattering in the Energy Range 30-{GeV} to 345-{GeV}

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Nucl.Phys.B 217 (1983) 285-335, 1983.

Inspire Record 182455 DOI 10.17182/hepdata.7556

Differential cross sections for π − p and pp elastic scattering have been measured at incident momenta ranging from 30 to 345 GeV and in the t range 0.002 (GeV/ c ) 2 ⩽ | t | ⩽ 0.04 (GeV/ c ) 2 . From the analysis of the data, the ratio ϱ ( t = 0) of the real to the imaginary parts of the forward scattering amplitude was determined together with the logarithmic slope b of the diffraction cone.

Measurements of $\pi^- p$ Forward Elastic Scattering at High-energies

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Phys.Lett.B 109 (1982) 111, 1982.

Inspire Record 166767 DOI 10.17182/hepdata.31011

The differential cross section of π − p scattering has been measured in the energy region 100–345 GeV and in the t -range 0.002<| t |< 0.04 (GeV/ c ) 2 . The real part of the π − p scattering amplitude has been extracted from the data. The results show that the real part continues to increase with energy. The energy dependence of the slope parameter has also been determined. The shrinkage found expressed in terms of the slope of the pomeron trajectory is2 α ′ p =0.23±0.04 (GeV/ c ) −2 . This agrees with the energy dependence found at larger| t |-values.

Measurements of $\pi^- p$ Elastic Scattering in the Coulomb Interference Region at High-energies

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Phys.Lett.B 77 (1978) 438-442, 1978.

Inspire Record 131449 DOI 10.17182/hepdata.27428

The differential cross section has been measured at 30, 50, 80, 100, 120 and 140 GeV/ c for 0.002 < | t | < 0.04 ( GeV / c ) 2 . The results show that the π − p real part goes from negative to positive values below 80 GeV/ c . The slope parameter in the t -region measured is significantly higher than what has been found − t = 0.2 (GeV/ c ) 2 .
