夸克-反夸克静势的长程行为。应用于轻夸克介子和重夸克偶子

Long-distance behavior of the quark-antiquark static potential. Application to light-quark mesons and heavy quarkonia

P. Gonzalez

摘要:

从唯象的角度分析了从轻夸克到重夸克介子谱的海对对夸克-反夸克静势的屏蔽效应。从高激发态光夸克介子谱出发,提出屏蔽静电势的普遍形式。这种势被成功地应用于重夸克偶素。我们的研究结果表明,X(4260)的4s状态的粲偶素和5s bottomonium共振的可能存在约10748 MeV的分配。

英文摘要:

Screening effects from sea pairs on the quark-antiquark static potential are analyzed phenomenologically from the light-quark to the heavy-quark meson spectra. From the high excited light-quark meson spectrum a universal form for the screened static potential is proposed. This potential is then succesfully applied to heavy quarkonia. Our results suggest the assignment of X(4260) to the 4s state of charmonium and the possible existence of a 5s bottomonium resonance around 10748 MeV.
