$\pi^{-} + p$ elastic scattering in the neighbourhood of $N^{*}_1/2$ (2190)

Busza, W. ; Davis, D.G. ; Duff, B.G. ; et al.
Nuovo Cim.A 52 (1967) 331-341, 1967.
Inspire Record 1185326 DOI 10.17182/hepdata.37568

Elastic π−+p differential cross-section data are presented at the incident-pion momenta 1.72, 1.89, 2.07, 2.27 and 2.46 GeV/c. Resonant behaviour in the coefficients of a Legendre polynomial expansion indicates G- or H-wave resonance. Further analysis using an energy-dependent parametrization of G- and H-waves shows the results to be compatible with the 7−/2 assignment for the , but equally acceptable solutions are obtained with the inclusion of an additional 9+/2 resonance contribution.

Pi-minus p elastic scattering at 2.26 gev/c

The elastic scattering of negative pions on protons at 2.26 GeVc has been studied using the Lawrence Radiation Laboratory 72-in. hydrogen-filled bubble chamber. The elastic scattering cross section is found to be 8.91±0.24 mb. The forward diffraction peak is well fitted by an exponential in the square of the four-momentum transfer, and the slope is found to be 8.8±0.1 GeV−2. The differential cross section is parametrized in terms of three models: optical, strong-absorption, and two-slope. It is found that the two-slope model affords the best description of the data and also does very well in predicting the polarization data of other experiments. The best-fit parameters for all three models are given. In addition, the amplitudes associated with the best fits are given for the strong-absorption and the two-slope models.

Pi-plus-minus p elastic scattering in the 2-gev region

Busza, W. ; Duff, B.G. ; Garbutt, D.A. ; et al.
Phys.Rev. 180 (1969) 1339-1348, 1969.
Inspire Record 55449 DOI 10.17182/hepdata.6227

π±p elastic differential cross sections in the momentum range 1.72-2.80 GeV/c have been measured at the proton synchrotron "NIMROD" of the Rutherford High Energy Laboratory. The results are tabulated, and analyses of the differential cross sections employing optical models and Legendre polynomial expansions are advanced. A critical discussion of a recent interpretation of differential-cross-section structure in terms of interference between resonant and background amplitudes is presented.
