Bound state formation in the $DDK$ system

Abstract

We study the DDKDDK system in a coupled channel approach, by including DDsηDD_s\eta and DDsπDD_s\pi, and find that the dynamics involved in the system forms a bound state with isospin 1/21/2 and mass 41404140 MeV when one of the DKDK pair is resonating in isospin 0, forming the Ds0(2317)D^*_{s0}(2317). The state can be interpreted as a DDs0(2317)DD^*_{s0}(2317) molecule like state with exotic quantum numbers: doubly charged, doubly charmed, and with single strangeness.
