Spin observables in p-barp {yields} {lambda}{lambda} and density-matrix constraints

The positivity conditions of the spin density matrix constrain the spin observables of the reaction p-barp {yields} {lambda}-bar{lambda}, leading to model-independent, non-trivial inequalities. The formalism is briefly presented and examples of inequalities are provided.
