Surveying exotic pentaquarks with the typical $QQqq\bar{q}$ configuration

Understand

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.
