光谱学理论综述

Theory Overview on Spectroscopy

Ahmed Ali

摘要:

本文从理论上综述了粲夸克和美夸克区的奇异光谱。这些态是$e^+e^-$和强子对撞机的意外收获,它们中的大多数还没有被找到。我们认为,其中一些态,特别是$Y_b(10890)$和最近发现的状态$Z_b(10610)$和$Z_b(10650)$,由Belle合作发现的四夸克态$[bq][\bar{b}\bar{q}]$,与$q=u,d$轻夸克的优秀候选者。本文综述了四夸克态背景下Belle数据的理论分析。

英文摘要:

A theoretical overview of the exotic spectroscopy in the charm and beauty quark sector is presented. These states are unexpected harvest from the $e^+e^-$ and hadron colliders and a permanent abode for the majority of them has yet to be found. We argue that some of these states, in particular the $Y_b(10890)$ and the recently discovered states $Z_b(10610)$ and $Z_b(10650)$, discovered by the Belle collaboration are excellent candidates for tetraquark states $[bq][\bar{b}\bar{q}]$, with $q=u,d$ light quarks. Theoretical analyes of the Belle data carried out in the tetraquark context is reviewed.
