A doubly charmed strange molecule from coupled-channel dynamics

We investigate a doubly charmed molecular state $T_{cc\bar{s}}$ with $C=+2$, $\mathcal{S}=+1$, and $I=1/2$ in an off-shell coupled-channel formalism. Constructing the interaction kernel from a meson-exchange model based on an effective Lagrangian and solving the coupled-channel scattering equation in the Blankenbecler-...
