Charmionium chart


 
Present state of the knowledge about charmionium energetical states (i.e. mesons which is built from  c quark and  c antiquark) and trasitions between these states. Distances between energetic levels according to difference of the masses - for example J/? meson's mass in (1S) state is  m=3097 MeV and in (2S) state - m=3686 MeV.

Marking g* means decays with presence of virtual photons, including decays to e+e- and  µ+µ-.
Uncwrtiaun states and transitions are marked with dashed lines
