Here the Y(4660) is assumed to be either a two-body bound state of the f_0(980), itself a bound state of K and Kbar, and the psi'= psi(2s), or a three-body bound state of psi', K, and Kbar. In particular, we investigate in detail the interplay of the various scales inherent in the problem, namely the f_0 binding energy, the Y binding energy, and the K-psi' scattering length. This allows us to understand under which circumstances the substructure of the f_0(980) can be neglected in the description of the Y(46","authors_text":"C. Hanhart, H.-W. Hammer, P.
