论文摘要
最近，LHCB合作报道了$ J/ψ$ Pairs的不变质量频谱中充满迷人的Tetraquark State $ X（6900）$。如果一个$ j/ψ$梅森被一个充满迷人的巴里昂取代，我们将获得一个充满迷人的五角大族候选人。在这项工作中，我们对S-Wave完全沉重的Pentaquark $ QQQQ \ bar {q} $进行了系统研究。根据我们在两个不同方案中的结果，我们进一步研究了它们的衰减行为。我们希望我们的研究将来有助于在未来实验中寻找这种异国情调的五角夸克州。
Very recently, the LHCb Collaboration reported a fully charmed tetraquark state $X(6900)$ in the invariant mass spectrum of $J/ψ$ pairs. If one $J/ψ$ meson is replaced with a fully charmed baryon, we obtain a fully charmed pentaquark candidate. In this work, we perform a systematic study on the mass spectra of the S-wave fully heavy pentaquark $QQQQ\bar{Q}$ in the framework of the chromomagnetic interaction model. Based on our results in two different schemes, we further investigate the decay behaviors for them. We hope that our study will be helpful in searching for such types of exotic pentaquark states in experiments in the future.
