| Abstract | We calculate the masses of chi(c)(2P) and chi(b)(3P) states with threshold corrections in a coupled-channel model. Here, the meson quarkonium core is augmented by higher Fock components due to pair-creation effects. According to our results, we interpret the resonances characterized by very small threshold corrections, like chi(b)(3P)'s, as almost pure quarkonia, and those states characterized by non-negligible threshold corrections, like the X(3872), as quarkonium cores plus meson-meson components. We also study the J/psi rho and J/psi omega hidden-flavor strong decays of the X(3872). The decays are calculated as the dissociation of one of these components (D-0(D) over bar (0)*) into a c (c) over bar state (J/psi) plus a light meson (rho or omega) in a potential model. In particular, our result for the ratio between the X(3872) -> J/psi omega and.1 J/psi rho widths (0.6) is compatible with the present experimental data (0.8 +/- 0.3) within the experimental error.
