含四夸克成分的隐魅分子态的预测

Predictions of the hidden-charm molecular states with four-quark component

Rui Chen, Xiang Liu, Yan-Rui Liu, Shi-Lin Zhu

摘要:

本文采用单π交换模型系统地研究了$T\bar{T}$型分子系统,其中$T$表示窄$J^P=1^+$ $D_1$介子或$2^+$ $D_2^*$介子,$\bar{T}$是它的反粒子.利用这些有效势,我们试图找到相应体系的束缚态解,这为是否存在$T\bar{T}$型分子态提供了重要信息。根据我们的分析,我们预测一些$T\bar{T}$型分子状态,可能会在未来的实验,如LHCb和即将到来的BelleII。

英文摘要:

In this work, we study the $T\bar{T}$-type molecular systems systematically via one pion exchange model, where $T$ denotes the narrow $J^P=1^+$ $D_1$ meson or $2^+$ $D_2^*$ meson and $\bar{T}$ is its antiparticle. With the effective potentials, we try to find the bound state solutions of the corresponding systems, which provide crucial information of whether there exist the $T\bar{T}$-type molecular states. According to our analysis, we predict some $T\bar{T}$-type molecular states which may be accessible at future experiments like LHCb and forthcoming BelleII.
