标题： On the nature of the K*2(1430), K*3(1780), K*4(2045), K*5(2380) and K*6 as K*--multi-rho states

摘要： 我们证明，$K^*_2(1430)$、$K^*_3(1780)$、$K^*_4(2045)$、$K^*_5(2380)$以及尚未发现的$K_6^*$共振基本上是由越来越多的$\rho(770)$和一个$K^*(892)$介子组成的分子。 该想法基于这样一个事实，即自旋对齐的s波矢量-矢量相互作用对于$\rho\rho$和$K^*\rho$都非常强。 我们扩展了一项近期的工作，其中几个共振作为多$\rho(770)$分子出现，扩展到包括$K^*(892)$进入系统的奇异领域。 共振结构出现在多体散射振幅中，这些振幅通过使用Faddeev方程的固定中心近似，以单位二体矢量-矢量散射振幅来计算。 显示英文摘要

摘要： 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 $\rho(770)$ and one $K^*(892)$ mesons. The idea relies on the fact that the vector-vector interaction in s-wave with spins aligned is very strong both for $\rho\rho$ and $K^*\rho$. We extend a recent work, where several resonances showed up as multi-$\rho(770)$ molecules, to the strange sector including the $K^*(892)$ into the system. The resonant structures show up in the multi-body 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.
