  "abstract": "We extend the Fixed Center Approximation (FCA) to the Faddeev Equations for the $\\bar{K} NN$ system with S=0, including the charge exchange mechanisms in the $\\bar{K}$ rescattering which have been ignored in former works within the FCA. We obtain similar results to those found before, but the binding is reduced by 6 MeV. At the same time we also evaluate the explicit contribution the $\\pi N \\Sigma$ intermediate state in the three body system and find that it produces and additional small decrease in the binding of about 3 MeV. The system appears bound by about 35 MeV and the width omitting two body absorption, is about 50 MeV.",
