| description | Abstract Recently, the LHCb Collaboration has measured two decay processes $$B^0\rightarrow \bar{D}^0D_s^+\pi ^-$$ B 0 → D ¯ 0 D s + π - and $$B^+\rightarrow D^-D_s^+\pi ^+$$ B + → D - D s + π + related to isospin symmetry, where two new open-flavored tetraquark states $$T_{c\bar{s}}(2900)^0$$ T c s ¯ ( 2900 ) 0 and $$T_{c\bar{s}}(2900)^{++}$$ T c s ¯ ( 2900 ) + + that belong to an isospin triplet were observed in the $$D_s^+\pi ^-$$ D s + π - and $$D_s^+\pi ^+$$ D s + π + invariant mass distributions. In this work, we have investigated the validity of the process $$\bar{B}_s^0\rightarrow K^0D^0\pi ^0$$ B ¯ s 0 → K 0 D 0 π 0 as the promising process to confirm the existence of $$T_{c\bar{s}}(2900)^0$$ T c s ¯ ( 2900 ) 0 resonance. Taking into account the tetraquark state $$T_{c\bar{s}}(2900)$$ T c s ¯ ( 2900 ) , as well as intermediate resonances $$K^*(892)$$ K ∗ ( 892 ) , $$K_0^*(1430)$$ K 0 ∗ ( 1430 ) , and $$K_2^*(1430)$$ K 2 ∗ ( 1430 ) , it has been shown that a clear peak of the open-flavored tetraquark $$T_{c\bar{s}}(2900)$$ T c s ¯ ( 2900 ) appears in the $$K^0D^0$$ K 0 D 0 invariant mass distribution of the process $$\bar{B}_s^0\rightarrow K^0D^0\pi ^0$$ B ¯ s 0 → K 0 D 0 π 0 , which could be tested by future experiments. |
