Vector meson-vector meson interaction in a hidden gauge unitary approach

Understand

The formalism developed recently to study vector meson--vector meson interaction, and applied to the case of $\rho\rho$, is extended to study the interaction of the nonet of vector mesons among themselves.

• The interaction leads to poles of the scattering matrix corresponding to bound states or resonances.
• We show that 11 states (either bound or resonant) get dynamically generated in nine strangeness-isospin-spin channels.
• Five of them can be identified with those reported in the PDG, i.e., the $f_0(1370)$, $f_0(1710)$, $f_2(1270)$, $f'_2(1525)$, and $K^*_2(1430)$.
