Real Parts of the Pion-Proton Forward Scattering Amplitude

Engelmann, T.R. ; Hendrick, R.E. ;

Phys.Rev.D 16 (1977) 2891, 1977.

Inspire Record 119142 DOI 10.17182/hepdata.75552

The most recent total-cross-section data are used to calculate real parts of the forward elastic π±p scattering amplitudes from threshold to 240 GeV/c. Using statistical and systematic uncertainties of the total cross sections and their momenta, along with uncertainties of the subtraction and coupling constants, unphysical cuts, and cross-section extrapolations, we calculate the uncertainties of the real amplitudes. Our results are compared to experimental and other theoretical determinations of the π±p forward real amplitudes.

Amalgamation of Meson - Nucleon Scattering Data

Kelly, R.L. ; Cutkosky, R.E. ;

Phys.Rev.D 20 (1979) 2782, 1979.

Inspire Record 140207 DOI 10.17182/hepdata.76310

We present a series of numerical and statistical techniques for interpolating and combining ("amalgamating") data from meson-nucleon scattering experiments. These techniques have been extensively applied to πp elastic and charge-exchange differential-cross-section and polarization data in the resonance region. The amalgamation is done by fitting a momentum- and angle-dependent interpolating surface to the data over a moderately narrow momentum range, typically ∼150 MeV/c, using the interpolating surface to shift data in a narrower central momentum region into fixed angular bins at a predetermined central momentum, and then statistically combining the data in each bin. The fitting procedure takes into account normalization errors, momentum calibration errors, momentum resolution, electromagnetic corrections, threshold structure, and inconsistencies among the data. The full covariance matrix of the amalgamated data is calculated, including contributions of statistical error, systematic error, and interpolation error. Techniques are presented for extracting from the covariance matrix information on the collective statistical fluctuations which correlate the errors of the amalgamated data. These fluctuations are described in terms of "correlation vectors" which facilitate the use of the amalgamated data as input for resonance-region phenomenology.

Differential cross-section of the π−+p → π0+n process at 930 MeV

Bigi, A. ; Carrara, R. ; Zanello, D. ;

Nuovo Cim. 34 (1964) 878-882, 1964.

Inspire Record 1498655 DOI 10.17182/hepdata.75447

A bubble chamber study of π-p charge-exchange scattering at 930 MeV is reported. The forward differential cross-section is derived and compared with the result obtained on the basis of dispersion relations and the charge-independence hypothesis. Satisfactory agreement is obtained.
