| contents | Recently, the LHCb Collaboration has measured the processes $B^0\to\bar{D}^0D_s^+π^-$ and $B^+\to\bar{D}^0D_s^+π^+$, where the $D_s^+π^-$ and $D_s^+π^+$ invariant mass distributions show the significant signals of two new open-flavor tetraquark states $T_{c\bar{s}}(2900)^0$ and $T_{c\bar{s}}(2900)^{++}$, as the two of the isospin triplet. In this work, we have investigated the process $Λ_b\to K^0D^0Λ$ by taking into account the intermediate nucleon resonance $N^*(1535)$ and the tetraquark state $T_{c\bar{s}}(2900)^0$, which could be dynamically generated by the interactions of the $D^*K^*/D^*_sρ$ and the pseoduscalar mesons-octet baryons, respectively. Our results show that a clear peak of the open-flavor tetraquark $T_{c\bar{s}}(2900)$ may appear in the $K^0D^0$ invariant mass distribution of the process $Λ_b\to K^0D^0Λ$, which could be tested by future experiments. |
