概要 We summarize the work [1] where we studied the few body system made of several rho(770) mesons. Based on the very strong interaction of two rho(770) vector mesons in spin 2 and isospin 0, we show that the resonances rho(3)(1690) (3(--)), f(4)(2050) (4(++)), rho(5)(2350) (5(--)) and f(6)(2510) (6(++)) can be interpreted as few body systems made of an increasing number of rho(770) particles. The fixed center approximation of the Faddeev equations is used in order to write the multi-body interaction in terms of the elementary two-body scattering amplitudes. Very good agreement with the experimental masses is found. An extension of the model to include also the interaction with K*(895) is discussed.
