- W4313557610 abstract "Motivated by the recent discovery of a charmonium $X(3960)$ in $B$ decays by the LHCb Collaboration, the likely existence of two bound/virtual states (denoted by ${X}_{soverline{s}}$ and ${X}_{qoverline{q}}$) below the ${D}_{s}^{+}{D}_{s}^{ensuremath{-}}$ and $overline{D}D$ mass thresholds has been reexamined recently. In this work, we employ the effective Lagrangian approach to calculate their production rates in $B$ decays utilizing triangle diagrams. Our results show that the production yields of ${B}^{+}ensuremath{rightarrow}{X}_{soverline{s}}{K}^{+}$ and ${B}^{+}ensuremath{rightarrow}{X}_{qoverline{q}}{K}^{+}$ are of the order of ${10}^{ensuremath{-}4}$, in agreement with the relevant experimental data, which indicates that, if the ${D}_{s}^{+}{D}_{s}^{ensuremath{-}}$ and $overline{D}D$ bound states indeed exist, they can be detected in $B$ decays. Moreover, we calculate the production rate of ${B}^{+}ensuremath{rightarrow}X(3960){K}^{+}$ assuming that $X(3960)$ is a resonant state of ${D}_{s}^{+}{D}_{s}^{ensuremath{-}}$ and find that it is also of the order of ${10}^{ensuremath{-}4}$ but a bit smaller than that as a ${D}_{s}^{+}{D}_{s}^{ensuremath{-}}$ bound state." @default.
