Title of talk:	Hadronic resonances made of many vector mesons
Abstract:	In previous works regarding the interaction of two vector mesons using the techniques of the chiral unitary approach, it was shown that the vector-vector interaction in s-wave with spins aligned is very strong both for rho-rho and K*-rho to the point to get dynamically the f2(1270) and K*2(1430) resonances. In the work presented in this talk we use the rho-rho and rho-K* interaction in spin 2 and isospin 0 channel to show that the resonances rho3(1690), f4(2050), rho5(2350) and f6(2510) and the strange K*2(1430), K*3(1780), K*4(2045), K*5(2380) and a not yet discovered K*6 are basically molecules of increasing number of rho(770) mesons (with also a K*(892) in the case of the strange states). We use the fixed center approximation of the Faddeev equations to write the multi-body interaction in terms of the two-body scattering amplitudes. We find the masses of the states very close to the experimental values.
