Study of the $B^{-}\to K^{-}\hat{I}\cdot \hat{I}{\cdot }_c$ decay due to the $D\bar{D}$ bound state

Xin-Qiang Li, Li-Juan Liu, En Wang +1

We study the $B^{-}\to K^{-}\hat{I}\cdot \hat{I}{\cdot }_c$ decay by taking into account the $S$-wave contributions from the pseudoscalar meson-pseudoscalar meson interactions within the unitary coupled-cha…
