アブストラクト: This year is the tenth anniversary of the observation of the X(3872)
charmonium-like state that put
an end to the era when heavy quarkonium was considered as a relatively
well established bound system
of a heavy quark and antiquark. Since 2003 every year has been
bringing discoveries of new particles with
unexpected properties, not fitting a simple qqar classification
scheme. The wealth of new results is mainly
due to the B-factories, Belle and BaBar, where data samples with
unprecedented statistics became available.
In this report we will describe the results that contribute
to the subject, discuss recent developments for low-lying states, then
we move to the open flavor thresholds
and beyond. We consider the charmonium- and bottomonium-(like) states
in parallel to stress similarities
between the observed phenomena in the two quarkonium sectors. Finally
we will discuss a future prospects
for this subject at high luminosity e+e colliders.
