| contents | Motivated by the discovery of the fully charmed tetraquark state $X(6900)$ in the invariant mass spectrum of $J/ψ$ pairs by the LHCb collaboration, this study explores the potential existence of fully heavy pentaquark states. We systematically investigate the low-lying s-wave fully heavy pentaquark states across all possible configurations. The classification of these states is performed using the Young-Yamounachi bases through the Young-tableau technique. We analyze the mass spectrum and magnetic moments of pentaquarks with quantum numbers $J^P$= $\frac{1}{2}^{\pm}$,$\frac{3}{2}^{\pm}$ and $\frac{5}{2}^{\pm}$ utilizing effective mass and screened charge schemes. Our findings are compared with various theoretical models, providing valuable insights for future experimental studies. |
