The branching fractions of the $\Upsilon(1S)$ inclusive decays into final states with a $J/\psi$ or a $\psi(2S)$ are measured with improved precision to be $\BR(\Upsilon(1S)\to J/\psi + {\rm anything})=(5.25\pm 0.13(\mathrm{stat.})\pm 0.25(\mathrm{sy

We study general features of three-meson bound states using the Y(4660) as an example. Here the Y(4660) is assumed to be either a two-body bound state of the f_0(980), itself a bound state of K and Kbar, and the psi'= psi(2s), or a three-body bound s
