Description
A precise description of pion-pion interactions at low energies is fundamental for many processes in hadronic physics. We present preliminary work, which introduces several improvements with respect to a previous dispersive analysis*. This includes a refined treatment of inelasticities, the introduction of G-waves, the study of Forward Dispersion Relations (FDRs) up to 1.6 GeV, and data description up to 1.8 GeV. From the FDR output, we extract resonance poles by means of continued fractions.
