Abstract

We show that the $K_{2}^{*} (1430)$ , $K_{3}^{*} (1780)$ , $K_{4}^{*} (2045)$ , $K_{5}^{*} (2380)$ , and a not-yet-discovered $K_{6}^{*}$ resonance are basically molecules made of an increasing number of $ρ (770)$ and one $K^{*} (892)$ mesons. The idea relies on the fact that the vector-vector interaction in the $s$ wave with spins aligned is very strong for both $ρ ρ$ and $K^{*} ρ$ . We extend a recent work, where several resonances showed up as multi- $ρ (770)$ molecules, to the strange sector including the $K^{*} (892)$ into the system. The resonant structures show up in the multibody scattering amplitudes, which are evaluated in terms of the unitary two-body vector-vector scattering amplitudes by using the fixed center approximation to the Faddeev equations.
