| Résumé : | A self-consistent calculation of the mass and coupling constants of the Y* (1.385 MeV) has been performed. The (πΛ), (πΣ), (KN) coupled channels are taken into account. Writing the amplitude matrix in the form ND-1, approximate calculations are given of the Nij(s) functions which are represented as pole terms; they depend on the parameters of the Y*. A self- consistent technique is employed; the calculated mass and decay widths are m(Y*)≈1.365 MeV, Γ(Y*→πΛ)≈40 MeV; Γ(Y*→πΣ)≈3 MeV. © 1966. |
