低于2 GeV的常规介子

Conventional mesons below 2 GeV

Francesco Giacosa

摘要:

我们简要回顾了2 GeV以下各种常规夸克-反夸克介子的状况,并概述了一些悬而未决的问题:奇异-反奇异轨道激发矢量介子的状况、轴张量介子(众所周知的张量介子的手征伙伴)的九等态的状况,以及赝张量扇区中的等标混合角,它最终可以代表手征异常的一种新表现。

英文摘要:

We briefly review the status of various conventional quark-antiquark mesons below 2 GeV and outline some open questions: the status of the strange-antistrange orbitally excited vector meson, the status of the nonet of axial-tensor mesons (chiral partners of the well known tensor mesons), and the isoscalar mixing angle in the pseudotensor sector, which can eventually represent a novel manifestation of the chiral anomaly.
