To determine the absolute rates of the reactions that give rise to resonances in physics of particles, it is necessary to use a dynamic theory of the strong interaction. However, to calculate the relative rates of different reactions that produce the same resonances, we can take advantage of isospin symmetry and the Clebsch-Gordan coefficients.
In this context, we seek to determine the relationship of the effective sections of the following interactions in relation to the ∆++ resonance, using the Clebsch-Gordan coefficients as a tool clue.
