Model-independent aspects of the reaction K ¯ + N → K + Ξ
Model-independent aspects of the reaction K ¯ + N → K + Ξ
Various model-independent aspects of the K¯¯¯N→KΞ reaction are investigated, starting from the determination of the most general structure of the reaction amplitude for Ξ baryons with JP=12± and 32± and the observables that allow a complete determination of these amplitudes. Polarization observables...

Various model-independent aspects of the K¯¯¯N→KΞ reaction are investigated, starting from the determination of the most general structure of the reaction amplitude for Ξ baryons with JP=12± and 32± and the observables that allow a complete determination of these amplitudes. Polarization observables are constructed in terms of spin-density matrix elements. Reflection symmetry about the reaction plane is exploited, in particular, to determine the parity of the produced Ξ in a model-independent way. In addition, extending the work of Biagi et al. [Z. Phys. C 34, 175 (1987)], a way of determining simultaneously the spin and parity of the ground state of Ξ baryons as well as those of the excited Ξ states is presented. |
