    "abstract": "The constraints imposed by symmetry on the open channels of dipositronium has\nbeen studied, and the symmetry-adapted lowest open channel of each quantum\nstate has been identified. Based on this study, the existence of two more 0^+\nbound states has been theoretically confirmed, and a 0^+ narrow resonance has\nbeen predicted. A variational calculation has been performed to evaluate the\ncritical strength of the repulsive interaction . Two 0^- states are found to\nhave their critical strengths very close to 1, they are considered as\ncandidates of new narrow resonances or loosely bound states .",
