    "abstract": "We have investigated the possible existence of a quasi-bound state for the\n\\Sigma -\\Sigma -\\alpha system in the framework of Faddeev calculations. We are\nparticularly interested in the state of total iso-spin T=2, since for an inert\n\\alpha particle there is no strong conversion to \\Xi -N-\\alpha or \\Lambda\n-\\Lambda -\\alpha possible. A \\Sigma -\\alpha optical potential based on Nijmegen\nmodel D and original \\Sigma -\\Sigma interactions of the series of Nijmegen\npotentials NSC97 as well a simulated Gaussian type versions thereof are used.\nOur investigation of the \\Sigma -\\Sigma -\\alpha system leads to a quasi bound\nstate where, depending on the potential parameters, the energy ranges between\n-1.4 and -2.4 MeV and the level width is about 0.2MeV.",
