Recent measurements of differential and elastic cross-sections, slope parameters and ratios of the real and imaginary parts of the forward scattering amplitudes for pion-proton elastic scattering at 200 GeV/c have been fitted by using a simple Regge pole model with phenomenological residue functions. The computed results for total cross-sections have also been compared with the experimental data.

It is shown that the most recent measurements of differential cross-section at small momentum transfers, integrated and total cross-sections, and the slope of np elastic scattering from 100 to 400 GeV/c are successfully fitted by using the simple Regge pole model proposed by the authors several years ago.

The hyperon form factors obtained by using lattice quantum chromodynamics have been used in the Chou-Yang model in conjunction with the proton form factor obtained by parametrization of the experimental data including the most recent results to obtain differential cross-sections of hyperon-proton elastic reactions. The agreement with available experimental data verifies lattice QCD results at low momentum transfers.
