Description

A number of new states have been observed from the Belle experiment
ever since the discovery of the X(3872) in 2003
and related studies are still ongoing by using full Belle data set.
Here we report some of recent results on the charmonium and
charmoniumlike states, and also open charm production based on a large data sample recorded at the
Belle detector at the KEKB asymmetric-energy e+e- collider.
Those include the measurement of the absolute branching fraction CCbar
K in B decays, the observation of chi_c0(2P) candidate in e+e- -> J/psi
DDbar, the first search for Zc pair production in U(1S) and U(2S) decays and
in e+e- annihilation at Sqrt(s)=10.52, 10.58, and 10.867 GeV,Â
and the measurement of gamma gamma to eta_c(1S), etac_c(2S) in eta'
pi+pi-.
