Description
Belle experiment at the KEKB factory, originally dedicated to studies
of $B$ mesons, was proved to be a great place also for studying charm
physics. The QCD motivated measurements of spectroscopy, decays and
production of charmed and charmonium states were succesfully performed
at Belle and initiated a lot of theoretical work. In particular,
recent discoveries of charmonium-like resonances indicate a renaissance
of the $c \bar{c}$ spectroscopy. These so called $XYZ$ states do not
fit the conventional $c \bar{c}$ spectrum described, so far successfully,
by the quark models. This suggests that some of them might be exotic
and could realize an unproved area of QCD predictions.
