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 $…

Polarization transfer in $I ¨ ^{'} \to I ¨ I ¨ I ¨ $ : a complete spin density matrix analysis framework

Jiabao Gong, Guanyu Wang, Dongyu Yuan +7

A theoretical framework based on the Spin Density Matrix (SDM) formalism is developed to describe polarization transfer in the decay chain $e^+e^- \rightarrow Ï^\prime \rightarrow…

Study $I^_{c}^{+} \to I^ K ˉ^{0} I ¨ ^{+}$ and search for the low-lying baryons $I^ (1/ 2^{-})$ and $I^£ (1/ 2^{-})$

Ying Li, Wen-Tao Lyu, Guan-Ying Wang +3

Since searches for the low-lying excited baryons $I^ (1/ 2^{-})$ and $I^£ (1/ 2^{-})$ are crucial to deepening our understanding of the light baryon spectrum, we have investigated the Cabib…

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…
