Abstract

Using the Fixed Center Approximation to Faddeev equations we have investigated the DKKDKK and DKKˉDK\bar{K} three-body systems, considering that the Ds0(2317)D^*_{s0}(2317) acts as the heavy cluster in both cases, generated from the DKDK interaction in isospin 0. For the DKKˉDK\bar{K} system we have found evidence of a state with I(JP)=1/2(0)I(J^P)=1/2(0^-) and mass about 283328582833 - 2858 MeV, above the threshold of Ds0(2317)KˉD^*_{s0}(2317)\bar{K}. Our results indicate that this state is dominated by a Df0(980)Df_0(980) component, then it could be searched for in the ππD\pi \pi D invariant mass. On the other hand, no clear evidence related to a state from the DKKDKK interaction is found.
