The Production of Charm Pentaquark from B meson within SU(3) Analysis

We study the masses and production modes of pentaquark with the quark constituent $c\bar{q}qqq$, by the tridiquark-diquark model and systematical light flavor quark symmetry SU(3) analysis. The mass splittings show that the S-wave singly charm pentaquark $c\bar{u}dds$, $c\bar{d}usu$, $c\bar{s}udu$, and $c\bar{s}udd$ are below their strong decay thresholds, while $c\bar{u}dss,c\bar{d}uss$ with parity ${\frac{1}{2}}^{-}$ are near their strong decay thresholds, which imply the possibility of stable states. Furthermore, we discuss the production of the concerned 15 states from $B$ meson, the analysis within SU(3) symmetry yields the golden channels of production process, ${\bar{B}}_s^0\text{\hspace{0.17em}⁣}\text{\hspace{0.17em}⁣}\to F_{-1\mathrm{/}2}^{+}\bar{p},B^{-}\text{\hspace{0.17em}⁣}\text{\hspace{0.17em}⁣}\to F_{-3\mathrm{/}2}^{-}{\bar{\mathrm{\Lambda }}}^0$, which expected to be work worthily in b-factory.
