Poles in $π N$ scattering from forward dispersion relations and revised total cross-section data

José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira

We present a model-independent calculation of $π N$ forward dispersion relations and their analytic continuation to the complex plane, using a revised set of $π^{\pm} p$ total cross-s…

The unintuitive SU(3) flavor and chiral limits of hadron resonances

José Ramón Peláez, Pablo Rabán, Jacobo Ruiz de Elvira

Contrary to naive expectations, poles used to define hadron resonances rigorously in the physical world may not evolve continuously to become degenerate in the SU(3) $_{F}$ and chiral…
