粲偶素矢量共振的进一步证据

Evidence for further charmonium vector resonances

Eef van Beveren, George Rupp

摘要:

我们讨论了在D(s)* antiD(s)* 和Lambda(c)+ Lambda(c)-通道的开口处,反应e+ + e-> D* + antiD* 的产生截面中阈值信号的形状。此外,3D,5S,4D,6S,5D,7S,6D和8 S粲偶素矢量共振的证据,最近公布的数据的基础上,由BaBar合作。中心质量和共振宽度的估计。这些共振的确认将是将强子光谱学的精度水平提升到原子光谱学的一大步,对理论产生深远的影响。

英文摘要:

We discuss the shape of threshold signals in production cross sections of the reaction e+ + e- --> D* + antiD*, at the opening of the D(s)* antiD(s)* and Lambda(c)+ Lambda(c)- channels. Furthermore, evidence for the 3D, 5S, 4D, 6S, 5D, 7S, 6D, and 8S 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.
