The pion-pion scattering amplitude. III: Improving the analysis with forward dispersion relations and Roy equations
We complete and improve the fits to experimental ππ scattering amplitudes, both at low and high energies, that we performed in the previous papers of this series. We then verify that the corresponding amplitudes satisfy analyticity requirements, in the form of partial wave analyticity at low energies, forward dispersion relations (FDR) at all energies, and Roy equations belowK̄K threshold; the f...
متن کاملLow-energy pion-nucleon scattering
An analysis of low-energy charged pion-nucleon data from recent pp experiments is presented. From the scattering lengths and the Goldberger-Miyazawa-Oehme ~GMO! sum rule we find a value of the pion-nucleon coupling constant of f 50.075660.0007. We also find, contrary to most previous analyses, that the scattering volumes for the P31 and P13 partial waves are equal, within errors, corresponding ...
متن کاملThe Low Energy Expansion for Pion-Pion Scattering and Crossing Symmetry in Dispersion Relations
We show that a suitable setting for comparison of the low-energy representation for pion-pion scattering amplitudes, with dispersive representation for these amplitudes, is provided by certain manifestly crossing symmetric dispersion relations. We begin with a discussion of fixed-t dispersion relations and discuss the origin of crossing constraints that arise in this context when we consider re...
متن کاملIsospin breaking in low-energy pion-nucleon scattering.
Since isospin symmetry is only approximate, the discrepancy in this relation, D ; fCEX 2 sf1 2 f2dy p 2, is expected to be nonzero. Interesting physics lies in the violation of this relation beyond effects due to the hadronic mass differences and the Coulomb interaction. It is the purpose of this Letter to demonstrate that recent experimental data at low energies require a residual contribution...
متن کاملLow-energy Pion-nucleon Interaction and the Sigma-term *
A dispersion framework, appropriate for discussing the low-energy pion-nucleon interaction , is reviewed. Sensitivity of the isoscalar D-amplitude at the unphysical Cheng-Dashen point to input from different phase shift analyses and low-energy experiments is discussed.
