论文摘要
B Belleii，Barbar和LHCB等B因子强调了异国情调强子研究的重要性。在本文中，我们讨论了$ b $ ersons $ \ bar {c} q qqq $从$ b $ ersons中的$ b $中的$ b-factory中的单独抗衡pentaquark States的可能产生。关于这两种可能性的讨论是由以下假设驱动的：在这项工作中考虑的五夸克状态（称为最低的状态$ p _ {\ bar c} $）可能是绑定或不结合的。我们找到了用于生产五夸克接地状态的黄金通道，例如$ b^0 \ to {p} _ {\ bar {c} sudu}^{（\ prime）0}σ^0 $。我们进一步估算了从$ b $梅森腐烂的地面状态$ p _ {\ bar c} $生产的分支比率。因此，多个通道可用于实验，这可能消除了发现新的五夸克状态的某些障碍。
The b-factories, such as BelleII, BarBar and LHCb, emphasize the increasing importance of exotic hadron research. In this paper, we discuss the possible production of singly anti-charmed pentaquark states $\bar{c}q qqq$ from $B$ mesons in the b-factory under SU(3) symmetry analysis. Discussions of both possibilities have been driven by the hypothesis that the pentaquark state considered in this work, known as the lowest lying state $P_{\bar c}$, could be bound or unbound. We find the golden channels for the production of the pentaquark ground states, such as $B^0 \to {P}_{\bar{c}sudu}^{(\prime) 0}Σ^0$. We further estimate the branching ratios for the production of the ground states $P_{\bar c}$ from $B$ meson decays. Thus, multiple channels are available for experiments, which may remove certain obstacles to the discovery of new pentaquark states.
