Abstract: We discuss the shape of threshold signals in production cross sections of thereaction e+ + e-> D* + antiD*, at the opening of the Ds* antiDs* andLambdac+ Lambdac- channels. Furthermore, evidence for the 3D, 5S, 4D, 6S,5D, 7S, 6D, and 8S charmonium vector resonances is presented, on the basis ofdata recently published by the BaBar Collaboration. Central masses andresonance widths are estimated. Confirmation of these resonances would be ahuge step in lifting the precision level of hadron spectroscopy towards that ofatomic spectroscopy, with far-reaching consequences for theory.
