Searching for doubly charmed tetraquark candidates $T_{cc}$ and $T_{cc\bar{s}}$ in $B_c$ decays

Abstract

In this work, we propose to search for the exotic doubly charmed meson $T_{cc}^{+}$ and its analog $T_{cc\bar{s}}^{+}$ in $B_c^{+}$ decays, which provide a good environment for the formation of the exotic state containing double charm quarks. Within the molecular scheme, the production of $T_{cc}^{+}$ and $T_{cc\bar{s}}^{+}$ through various rescattering processes with different intermediate states are investigated. For the moderate values of model parameters, the branching ratios of $B_c^{+}$ decaying into $T_{cc}^{+}{\bar{D}}^0$, $T_{cc}^{+}{\bar{D}}^{\ast 0}$, $T_{cc\bar{s}}^{+}{\bar{D}}^0$ and $T_{cc\bar{s}}^{+}{\bar{D}}^{\ast 0}$ are estimated to be of the order of $10^{-7}$, $10^{-5}$, $10^{-6}$ and $10^{-4}$, respectively, which may be tested by future experiments.
