| Abstract: | In view of persisting discrepancy between experimental and theoretical results, specially in the weak radiative decays of∑ + andΞ 0, we analyse these decays within the framework of the QCD inspired quark-diquark model. On introducing a slightSU(6) breaking we obtainα(∑ +→p+γ)≈?0.9 which is in excellent agreement with experimental value. Other decays are also improved in this scheme. |
