The formalism developed recently to study vector mesonvector meson interaction, and applied to the case of ρρ, 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 strangenessisospinspin channels. Five of them can be identified with those reported in the PDG, i.e., the f0(1370), f0(1710), f2(1270), f′2(1525), and K∗2(1430). The masses of the latter three tensor states have been used to finetune the free parameters of the unitary approach, i.e., the subtraction constants in evaluating the vector meson vector meson loop functions in the dimensional regularization scheme. The branching ratios of these five dynamically generated states are found to be consistent with data. The existence of the other six states should be taken as predictions to be tested by future experiments.
