Nonleptonic and Weak-Electromagnetic Decays of Hyperons in the Pole Model

Abstract

An estimate is made for the contribution of the decuplet poles to the weak decays of hyperons using the Rarita-Schwinger formalism for spin- 3 2 fields. SU ( 3 ) symmetry is used in conjunction with the Gourdin-Salin model for the D - B - π and D - B - γ couplings. It is shown that the decuplet contribution is large for the parity-violating amplitudes. For weak-electromagnetic decays, this predicts asymmetry parameters which are at variance with earlier calculations. The decay rate for Σ + → p γ agrees well with the experimental result.
