Observation of a chi(c2)' candidate in gamma gamma --> DD production at belle.
S. Uehara, K Abe, I Adachi, H Aihara et autres
We report on a search for new resonant states in the process gamma gamma --> DD. A candidate C-even charmonium state is observed in the vicinity of 3.93 GeV/c2. The production rate and the angular distribution in the gamma gamma center-of-mass frame …
