论文摘要
我们系统地研究了使用夸克配置$ [\ bar c u] [u d c] $，$ [\ bar c d] [u u c] $和$ [\ bar c c c] [u u u d] $的隐藏障碍五夸克电流。它们的某些关系是使用狄拉克和颜色指数的FIERZ重排得出的，并且获得的结果用于研究$ p_c $状态的强衰减特性，为$ \ bar d^{（*）}σ_c$ hadroonic molecules。我们计算$ j/ψp$，$η_cp $，$χ_{c0} p $，$χ_{c1} p $，$ \ bar d^{（*）0}λ_c^+$，$χ_ σ_c^{++} $衰减通道。我们建议在$η_cp $ Channel和$ p_c（4440）/p_c（4457）$中搜索$ p_c（4312）$中的$ \ bar d^{0}λ_c^+$ channel中的$ p_c（4440）/p_c（4457）$。
We systematically study hidden-charm pentaquark currents with the quark configurations $[\bar c u][u d c]$, $[\bar c d][u u c]$, and $[\bar c c][u u d]$. Some of their relations are derived using the Fierz rearrangement of the Dirac and color indices, and the obtained results are used to study strong decay properties of $P_c$ states as $\bar D^{(*)} Σ_c$ hadronic molecules. We calculate their relative branching ratios for the $J/ψp$, $η_c p$, $χ_{c0} p$, $χ_{c1} p$, $\bar D^{(*)0} Λ_c^+$, $\bar D^{0} Σ_c^{+}$, and $\bar D^{-} Σ_c^{++}$ decay channels. We propose to search for the $P_c(4312)$ in the $η_c p$ channel and the $P_c(4440)/P_c(4457)$ in the $\bar D^{0} Λ_c^+$ channel.
