Improvement of Multichannel Amplitudes for the Pion-Pion Scattering Using the Dispersion Relations
Improvement of Multichannel Amplitudes for the Pion-Pion Scattering Using the Dispersion Relations is a scholarly work, published in 2013 in ''Few-Body Systems''. The main subjects of the publication include partial wave analysis, Uniformization, particle physics, Crossing, unitarity, pion, amplitude, consistency, quantum electrodynamics, optical dispersion, quark–gluon plasma, dispersion relation, scattering amplitude, physics, quantum chromodynamics, and scattering. The multichannel S- and P-wave amplitudes for the pion-pion scattering, constructed requiring analyticity and unitarity of the S-matrix and using the uniformization procedure, are elaborated using the dispersion relations with imposed crossing symmetry condition.
