where the T matrix element contains a sum over all intermediate states that contribute to the process. In terms of the individual decay matrix elements introduced earlier, the T matrix element can be written as

where the explicit kinematic factors from the initial-state flux and the density of final states for each of the decays are not factored into the T matrix so that we can make sure that it explicitly respects unitarity in each partial wave. In terms of the individual decay matrix elements introduced earlier, the T matrix element can be written as
