摘要:

奇异五夸克态的探索是一个热点问题,无论对理论工作者还是实验工作者来说,都充满了挑战和机遇。在这项工作中,我们专注于一类具有$QQqq\bar{q}$($Q=b,c$ ; $q=u,d,s$)组态的五夸克态,系统地估计了它们的质谱。特别地,我们的结果表明可能存在一些稳定的或窄的奇异五夸克态。显然,我们的研究为进一步的实验寻找$QQqq\bar{q}$五夸克态提供了有价值的信息。随着LHCb的运行和即将到来的Belle II,我们有理由相信这里的这些预测可以得到验证。

英文摘要:

As a hot issue, exploring exotic pentaquarks is full of challenges and opportunities for both theorist and experimentalist. In this work, we focus on a type of pentaquark with the $QQqq\bar{q}$ ($Q=b,c$; $q=u,d,s$) configuration, where their mass spectrum is estimated systematically. Especially, our result indicates that there may exist some stable or narrow exotic pentaquark states. Obviously, our study may provides valuable information for further experimental search for the $QQqq\bar{q}$ pentaquarks. With the running of LHCb and forthcoming Belle II, we have a reason to believe that these predictions present here can be tested.
