Role of the $\rho (1450)$ in low-energy observables from an analysis in the meson dominance approach

Gustavo Ávalos, Antonio Rojas, Marxil Sánchez +1

The $\rho (1450)$ vector meson (${\rho }^{\prime }$) is becoming increasingly important to properly describe precision observables. We analyse a set of decay modes and cross sections, in the lo…
