Abstract
Towards a better understanding of multi-strangeness physics, various aspects of hyperon pro- duction are investigated in the reactions K +N K+ and +N K+K+. First K + N K + () is treated in a model-independent manner and a minimum set of spin ob- servables is established that will determine the spin-parity of the produced (), two of the basic quantum numbers that specify a baryon. In addition, a calculation for all observables is done within a simple effective lagrangian model in an effort to learn about the reaction dynamics. Here S = 1 hyperon resonances contributions are reported which are important production mechanisms for baryons. The + N K + K + reaction has a more complicated spin structure and we derive the most general spin structures consistent with basic symmetry principles. The effect of parity conservation on spin observables is investigated. A gauge-invariant model is described which is consistent with the calculation for the K + N K + reaction.
