Descripción
A precise description of pion-pion interactions at low energies is
fundamental for many processes in hadronic physics. We present
preliminary work that introduces several improvements over a previous
dispersive analysis*. These include a refined treatment of
inelasticities, the introduction of G-waves, the study of Forward
Dispersion Relations (FDRs) up to 1.6 GeV, data description up to 1.8
GeV, and the study of the three most reliable solutions. From the FDR
output we extract resonance poles using continued fractions.
