International Workshop on Chiral Symmetry in Hadrons and Nuclei, Valencia, Spain, 21 - 24 June 2010, pp.206-209
Using a coupled channel unitary approach, combining the heavy quark spin symmetry and the dynamics of the local hidden gauge, we investigate the meson-meson interaction with hidden beauty. We obtain several new states of isospin I = 0: six bound states, and weakly bound six more possible states which depend on the influence of the coupled channel effects.
