Abstract

We study the masses and production modes of pentaquark with the quark constituent $c \bar{q} q q q$ $c\bar{q}qqq$ , by the tridiquark-diquark model and systematical light flavor quark symmetry SU(3) analysis. The mass spectrums show that the S-wave singly charm pentaquark $c \bar{n} n n n, c \bar{s} s s n, c \bar{n} s s n$ $c{\bar{n}}nnn,~c{\bar{s}}ssn,~c{\bar{n}}ssn$ and $c \bar{n} s n n$ $c{\bar{n}}snn$ $(n = u, d)$ $$(n=u,d)$$ are above their strong decay thresholds, while $c \bar{s} n n n$ $c{\bar{s}} nnn$ and $c \bar{s} s n n$ $c\bar{s} snn$ with parity ${\frac{1}{2}}^{-}$ $\frac{1}{2}^-$ are below 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, ${\bar{B}}_{s}^{0} \to F_{\bar{s} u d d}^{+} \bar{p}, B^{-} \to F_{\bar{u} d d s}^{-} {\bar{Λ}}^{0}$ ${\overline{B}}^0_s\rightarrow F_{\bar{s}udd}^{+} {\overline{p}},\ B^-\rightarrow F_{\bar{u}dds}^{-} {\overline{\Lambda }}^0$ , which expected to be work worthily in b-factory.
