Finding a clean process $B^{-} \to K^{-} D^{0} K^{0}$ to probe absolutely exotic four-quark states

Man-Yu Duan, Guan-Ying Wang, Yun Liang +3

Motivated by the observations of $T_{c s ˉ 0} (2900)^{0}$ and $T_{c s ˉ 0} (2900)^{++}$ , we propose to search for $\tcsbar^0$ in the cleaner process $B^{-} \to K^{-} D^{0} K^{0}$ . In the $…

The $B^{-} \to J / I ¨ I^\cdot^{'} K^{-}$ reaction and the $Y (4710)$ and $K_{0}^{*} (1430)$ contributions

Wen-Tao Lyu, Man-Yu Duan, De-Min Li +3

Motivated by the recent LHCb Collaboration analysis, we have investigated the process $B^{-} \to J / I ¨ I^\cdot^{'} K^{-}$ by considering the contributions from the resonances $Y (4710)$ and…

Theoretical study of the open-flavor tetraquark $T_{c s ˉ} (2900)$ in the process $B ˉ_{s}^{0} \to K^{0} D^{0} I ¨ ^{0}$

Wen-Tao Lyu, Man-Yu Duan, Xiaoyu Wang +2

Recently, the LHCb Collaboration has measured two decay processes $B^{0} \to D ˉ^{0} D_{s}^{+} I ¨ ^{-}$ and $B^{+} \to D^{-} D_{s}^{+} I ¨ ^{+}$ related to isospin symmetry, where two new open-flavor tetraq…

Explore the properties of $I^ (1670)$ in the Cabibbo-favored process $I^_{c}^{+} \to p K^{-} I ¨ ^{+}$ decay

Sheng-Chao Zhang, Man-Yu Duan, Wen-Tao Lyu +3

Recently, the Belle and LHCb Collaborations have measured the $I^_{c}^{+} \to p K^{-} I ¨ ^{+}$ decay and reported the $p K^{-}$ invariant mass distribution, which shows a clear cusp structure…

The $I^_{c}^{+} \to I^\cdot I ¨ ^{+} I^$ reaction and the $I^ a_{0}^{+} (980)$ and $I ¨ ^{+} I^ (1670)$ contributions

Man-Yu Duan, Wen-Tao Lyu, Chu-Wen Xiao +4

We study from the theoretical point of view the $I^_{c}^{+} \to I ¨ ^{+} I^\cdot I^$ reaction, recently measured by the Belle and BESIII Collaborations, where clear signals are observed for $a_0(…
