The study of the singly anti-charmed pentaquark production in b-factory

Abstract

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 $\bar{c}qqqq$ 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 $B^0\to P_{\bar{c}sudu}^{(\prime )0}{\Sigma }^0$. 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.
