Recent results include the measurement of B->D(*)pi+pi-pi-pi0 decays, with rates of ~1.8% observation of a significant omega pi^- substructure that appears to result from the decay of the rho' resonance, whose mass and width we determine as…
The recent measurements by CLEO Collaboration for the inclusive J/Psi and Psi(2S) production in Upsilon(1S) decay and our previous calculation are analyzed. The J/Psi momentum spectrum and the production ratio of Psi(2S) versus J/Psi favour…

The CLEO-c detector at CESR has begun to collect large data sets of $e^+e^- \to c\bar{c}$ events in the center-of-mass energy range $\sqrt{s}=3 - 5 $GeV that will greatly enhance the size of the world's data sets of events produced at charm…

Based on the data samples collected at the energies of $J/\psi$, $\psi(3686)$, $\psi(3770)$ and $\psi(4040)$ resonances with the BESIII detector at the BEPCII storage ring, we present charmonium decays in two aspects. One is the search for…
