摘要：

Based on reflection symmetry in the reaction plane, it is shown that measuring the transverse spin-transfer coefficient K-yy in the (K) over bar N -> K Xi reaction directly determines the parity of the produced cascade hyperon in a model-independent way as pi(Xi) = K-yy, where pi(Xi) = +/- 1 is the parity. This result based on Bohr's theorem provides a completely general, universal relationship that applies to the entire hyperon spectrum. A similar expression is obtained for the photoreaction gamma N -> K K Xi by measuring both the double-polarization observable K-yy and the photon-beam asymmetry Sigma. Regarding the feasibility of such experiments, it is pointed out that the self-analyzing property of the Xi s can be invoked, thus requiring only a polarized nucleon target.
