Abstract
Using the Fixed Center Approximation to Faddeev equations we have investigated the DKK and DKˉK three-body systems, considering that the D∗s0(2317) acts as the heavy cluster in both cases, generated from the DK interaction in isospin 0. For the DKˉK system we have found evidence of a state with I(JP)=1/2(0−) and mass about 2833−2858 MeV, above the threshold of D∗s0(2317)ˉK. Our results indicate that this state is dominated by a Df0(980) component, then it could be searched for in the ππD invariant mass. On the other hand, no clear evidence related to a state from the DKK interaction is found.
