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 $c\bar qqqq$, 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 $c\bar udds$, $c\bar dusu$, $c\bar sudu$, and $c\bar sudd$ are below their strong decay thresholds, while $c\bar u ds s, c \bar d uss$ 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, $\overline B^0_s\!\!\to F_{-1/2}^+ \overline p,\ B^-\!\!\to F_{-3/2}^- \overline \Lambda^0$, which expected to be work worthily in b-factory.
