论文摘要

LHCB合作报道了2020年$ J/ψ$ Pairs不变的质谱中充满迷人的Tetraquark State X(6900)。这一发现激发了我们进一步研究完全沉重的Pentaquark系统。在这项工作中,我们通过组成夸克模型中的变异方法系统地研究了地面完全沉重的Pentaquark系统的所有可能配置。根据我们的计算,我们进一步分析了夸克和对五角星质量的贡献之间的相对长度。我们认为在完全繁重的五角大车系统中不存在稳定的状态。我们希望我们的研究将有助于探索完全繁重的五角大族国家。

The LHCb collaboration reported a fully charmed tetraquark state X(6900) in the invariant mass spectrum of $J/ψ$ pairs in 2020. This discovery inspires us to further study the fully heavy pentaquark system. In this work, we investigate systematically all possible configurations for ground fully heavy pentaquark system via the variational method in the constituent quark model. According to our calculations, we further analyze the relative lengths between quarks and the contributions to the pentaquark masses from different terms of the Hamiltonian. We think no stable states exist in fully heavy pentaquark system. We hope that our study will be helpful to explore for fully heavy pentaquark states.
