Regge phenomenology of the $N^{\ast }$ and ${\Delta }^{\ast }$ poles

JPAC collaboration, J. A. Silva-Castro, C. Fernandez-Ramirez +8

We use Regge phenomenology to study the structure of the poles of the $N^{\ast }$ and ${\Delta }^{\ast }$ spectrum. We employ the available pole extractions from partial wave analysis of meson scatter…
