    "abstract": "Under certain circumstances, a three-body decay width can be approximated by\nan integral involving a product of two off-shell two-body decay widths. This\n``angle-average\u0027\u0027 approximation is used to calculate the $\\pi NN$ decay width\nof the $d^*(J^\\pi=3^+, T=0)$ dibaryon in a simple $\\Delta^2$ model for the most\nimportant Feynman diagrams describing pion emissions with baryon-baryon recoil\nand meson retardation. The decay width is found to be about 0.006 (0.07, 0.5)\nMeV at the $d^*$ mass of 2065 (2100, 2150) MeV for input dynamics derived from\nthe Full Bonn potential. The smallness of this width is qualitatively\nunderstood as the result of the three-body decay being ``third forbidden\u0027\u0027. The\nconcept of $\\ell$ forbiddenness and the threshold behavior of a three-body\ndecay are further studied in connection with the $\\pi NN$ decay of the dibaryon\n$d\u0027(J^\\pi=0^-, T=0 or 2)$ where the idea of unfavorness has to be introduced.\nThe implications of these results are briefly discussed.",
