QCD'04: Recent Results from Belle
Abstract
The huge data sample accumulated at the KEKB storage ring allows for dedicated analyses in charm spectroscopy. A new, narrow resonance with a mass of 3.872 was found in decays of B mesons. Its properties remain unexplained. Results on various properties of the resonances have been updated. Older results on the unexpectedly large cross section for double charmonium production in annihilation have been confirmed and a refined analysis is presented.
