摘要：We present a recent study of vector meson-vector meson interaction using a unitary approach based on the hidden-gauge Lagrangians. We find that 11 states get dynamically generated, corresponding to poles of the scattering matrices on the second Riemann sheet. Five of them are associated to the f0(1370), f0(1710), f2(1270), f′2(1525), and K∗2 (1430), by comparing the mass, width, and decay pattern of these states with those of their experimental counterparts. Six others with the quantum numbers of h1, a0, b1, a2, K∗0 , and K1 can not be clearly identified with any experimentally observed resonances and should be taken as predictions to be tested by future experiments.
