摘要
We discuss the shape of threshold signals in production cross sections of the reaction e(+)e(-) -> D*(D) over bar*, at the opening of the D-s*(D) over bar (s)* and A(c)(+)A(c)(-) channels. Furthermore, evidence for the psi(3D), psi(5S), psi(4D), psi(6S), psi(5D), psi(7S), psi(6D), and psi(8S) new charmonium vector resonances is presented, on the basis of data recently published by the BABAR Collaboration. Central masses and resonance widths are estimated. Confirmation of these resonances would be a huge step in lifting the precision level of hadron spectroscopy towards that of atomic spectroscopy, with far-reaching consequences for theory.
