Determination of the Spins and Parities of Resonances

Abstract

The properties of angular-momentum tensors described in a previous paper are used to develop tests for the spins and parities of resonances. Fermion resonances decaying into particles of spin zero and spin one-half or spin zero and spin three-halves and boson resonances decaying into particles of spin zero and spin one are considered in some detail. Attention is given to angular correlations between production and decay configurations, both generally and in special cases such as forward production, low-energy production, and peripheral collisions. A moment analysis of the decay distributions is developed.
