Abstract

Positivity constraints have proved to be important for spin observables of exclusive reactions involving polarized initial and final particles. Attention is focused on the photoproduction of pseudoscalar mesons from spin $1 / 2$ baryons, more specifically $γ N \to K Λ, γ N \to K Σ$ , for which new experimental data are becoming available.
