1. The Renaissance in Hadron Spectroscopy
Quite a number of new narrow states just in the last two years!

2. Charmonium Charmonium states are being seen in e+e- annihilation
B decay
two-photon collisions,
hadronic production
pp annihilation
It is the access to a very broad variety of quantum number
JPC , many cross-checks, robust evidence and systematics
controls of measurements which is making the field lively and interesting!

3. The X(3872) New state discovered by Belle in
BK (J/+-), J/µ+µ- or e+e-
X(3872) seen also by CDF/D0
M =  0.6  0.5 MeV
 2.3 MeV (90 % C.L.)
M =  0.7  0.4 MeV

4. Charmonium States above the DD threshold
The energy region above the DD threshold at 3.73 GeV is very poorly known. Yet this region is rich in new physics.
The structures and the higher vector states ((3S), (4S), (5S) ...) observed by the early e+e- experiments have not all been confirmed by the latest, much more accurate measurements by BES. It is extremely important to confirm the existence of these states, which would be rich in DD decays.
This is the region where the first radial excitations of the singlet and triplet P states are expected to exist.
It is in this region that the narrow D-states occur.

5. The hc(1P1): the less established under threshold
Precise measurements of the parameters of the hc give
extremely important information on the spin-dependent
component of the qq confinement potential. A
comparison of the hc mass with the masses of the triplet P
states measures the deviation of the vector part of the qq
interaction from pure one-gluon exchange.
Measurement of the total width and partial width to
c+ will provide anestimate of the partial width to gluons.
The detection and measurement of this resonance require
high statistics and excellent beam resolution.
Central part of experimental program of PANDA at GSI.
