The relative importance of Jp = Q\* baryon resonances in nonleptonic hyperon decays is investigated within a dispersion relation formulation of the current algebra-PCAC method with a view to establishing which resonances can be neglected. The dispersion relation formulation is reviewed, equal-time c
Making use of an identity transformation independent of a nuclear model, we represent the 2Ξ½Ξ²Ξ²amplitude as a sum of two terms. One term accounts for most of the sensitivity of the original 2Ξ½Ξ²Ξ²-amplitude to g pp for realistic g pp 1 (with g pp being the ratio of the triplet and singlet p-p interacti
The question of the vanishing of renormalization constants Z, and Z, as conditions for compositeness is looked at once more both from the viewpoint of dispersion theory and field theory. Careful consideration is given to the formulation of the idea of a composite particle as one for which there exis
