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