Search for a $D\bar{D}$ bound state in the ${\Lambda }_b\to \Lambda D\bar{D}$ process

Le-Le Wei, Hong-Shen Li, En Wang +3

We have investigated the process of ${\Lambda }_b\to \Lambda D\bar{D}$, by taking into account the contributions from the $s$-wave $D\bar{D}$ interaction within the coupled-channel unitary approac…
