Description
We present the latest results on the production and decays of psi(3770) and decays of open charm from BESII and CLEO-c experiments. BES observed anomalous line shape of cross sections for e+e- --> hadrons between 3.65 3.872 GeV and also measured line shapes of DD-bar production and the ratio of the production rates of D+D- and D0D0-bar at psi(3770) resonance. CLEO-c measured Ds decay constants from 600 pb-1 data near 4.17 GeV and measured absolute branching fractions for exclusive Ds semileptonic decays.
