Abstract
We have made a study of helicity formalisms for two-body \ensuremath{\rightarrow} three-body reactions. We present what we feel is an improvement in the formalism of Namyslowski, Razmi, and Roberts, both in accuracy and in manageability. Also, we present the results of an application of the formalism to the reaction ${K}^{\ensuremath{-}}n\ensuremath{\rightarrow}{\ensuremath{\Sigma}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{\ensuremath{-}}$ in an isobar model with sequential decays through intermediate $\ensuremath{\Lambda}$ and $\ensuremath{\Sigma}$ resonances. We find some appreciable effects due to boson symmetrization.
