Abstract
A general method is described for the measurement of the polarization and alignment of a particle of arbitrary spin from the analysis of its three-body decays. This method provides a procedure for the determination of spin and parity of the decaying system which is independent of the dynamics of the decay process. The procedure is closely related to the one currently used for two-body reactions except that the normal to the decay plane replaces the center-of-mass momentum as an analyzer. The general formalism is developed and illustrated by two examples: three-pion decays and baryon-two-pion decays.Keywords
