论文摘要
在该过程中的$ t_ {c \ bar {s} 0} 0}^{0/++} $的最新观察中的启发$ t_ {c \ bar {s} 0} 0}^{0} $ in a $ d^{*} k^{*} $ molecule scenario和$ t_ {c \ bar {s} 0} 0}^0}^{0}^{0} \ to d^0} k^0} k^{0} k^{0} k^{0} k^0} $， $ d_ {s}^{+}π^{ - } $，$ d_ {s}^{*+}ρ^{ - } $，$ d_ {s1}^{（\ prime）+}+}π^{ - } { - } $我们的估计表明，$ t_ {c \ bar {s} 0}^{0} \ to d_s^+π^ - $的宽度是可观察到的，并且$ t_ {c \ bar {s} 0} 0} 0}^{0}^{0} $ d^0k^0k^0k^0 $ $ t_ {c \ bar {c \ bar {c \ bar {c \ bar {c \ bar {c \ bar {c \ bar {c \ bar {c \ bar）的主要衰减模式。 Considering the isospin symmetry, we proposed to search $T_{c\bar{s}0}(2900)^{++}$ in the $D^+ K^+$ invariant mass distributions of the process $B^+ \to D^+ D^- K^+$, where some preliminary experimental hints have been observed by LHCb Collaboration.
Inspired by the recent observations of $T_{c\bar{s}0}^{0/++}$ in the the processes $B^0\to\bar{D}^0 D_s^+ π^-$ and $B^+\to D^- D_s^+ π^+$ by LHCb Collaboration, we investigate the decay properties of the $T_{c\bar{s}0}^{0}$ in a $D^{*}K^{*}$ molecule scenario, and the widths of $T_{c\bar{s}0}^{0}\to D^{0}K^{0}$, $D_{s}^{+}π^{-}$, $D_{s}^{*+}ρ^{-}$, $D_{s1}^{(\prime)+}π^{-}$, and $D^{*0}(Dπ)^{0}$ are estimated. Our estimations indicate that the width of $T_{c\bar{s}0}^{0} \to D_s^+ π^-$ is sizable to be observed and the dominant decay mode of $T_{c\bar{s}0}^{0}$ is $D^0K^0$. Considering the isospin symmetry, we proposed to search $T_{c\bar{s}0}(2900)^{++}$ in the $D^+ K^+$ invariant mass distributions of the process $B^+ \to D^+ D^- K^+$, where some preliminary experimental hints have been observed by LHCb Collaboration.
