The Y(4260) and Y(4360) enhancements within coupled-channels
Puzzling structures have been observed in the charmonium energy region, namely the Y(4260) and the Y(4360), that cannot be easily accommodated within quark model frameworks. The proximity of nearby dominant hadronic thresholds suggests that they play an important role in the formation of the enhance...
