We calculate the masses of the resonances D_{s0}^*(2317) and D_{s1}(2460) as well as their bottom partners as bound states of a kaon and a D^*- and B^*-meson, respectively, in unitarized chiral perturbation theory at next-to-leading order. After fixi

Evidence that the Y(4660) is a f(0)(980)psi-prime bound state

Autor: Guo, F.-K., Hanhart, Chr., Meissner, U.G.

Publikováno v: Physics letters / B 665, 26-29 (2008). doi:10.1016/j.physletb.2008.05.057

We demonstrate that the experimental information currently available for the Y(4660) is consistent with its being an f(0)(980)psi' molecule. Possible experimental tests of our hypothesis are presented. (C) 2008 Elsevier B.V. All rights reserved.
