Study of the DKK and DKK¯ systems
AbstractUsing the fixed center approximation to Faddeev equations, we investigate the DKK and DKK¯ three-body systems, considering that the DK dynamically generates, through its I=0 component, the Ds0*(2317) molecule. According to our findings, for the DKK¯ interaction we find evidence of a state I(JP)=1/2(0-) just above the Ds0*(2317)K¯ threshold and around the Df0(980) threshold, with mass of about 2833–2858 MeV, made mostly of Df0(980). On the other hand, no evidence related to a state from the DKK interaction is found. The state found could be seen in the ππD invariant mass.
