Título: | Nature of the K-2*(1430), K-3*(1780), K-4*(2045), K-5*(2380), and K-6* as K*-multi-rho states |
Autor: | Yamagata-Sekihara, J. CSIC; Roca, Luis; Oset, Eulogi CSIC ORCID | Fecha de publicación: | 15-nov-2010 | Editor: | Institute of Physics Publishing | Citación: | Physical Review - Section D - Particles and Fields 82 (9): 094017 (2010) | Resumen: | 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 the s wave with spins aligned is very strong for both 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 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. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevD.82.094017 | URI: | http://hdl.handle.net/10261/33083 | DOI: | 10.1103/PhysRevD.82.094017 | ISSN: | 1550-7998 |
