Final state hyperon-nucleon interaction in strangeness photoproduction of the deuteron is investigated making use of the covariant reaction formalism and the P –matrix approach to the YN system. Remarkably simple analytical expression for the amplitude is obtained. Pronounced effects due to final state interaction are predicted including the manifestation of the 2.13 GeV resonance.

a [ The two nucleon emission process off 3 He induced by medium energy electrons has been theoretically analyzed using realistic three-nucleon wave functions and taking the final state interaction into account. Various kinematical conditions have been considered in order to clarify the question whether the effects of the final state interaction could be minimized by a proper choice of the kinem...

We clarify under what circumstances the nucleon–nucleon final state interaction fixes the energy dependence of the total cross–section for the reaction NN → NNx close to production threshold, where x can be any meson whose interaction with the nucleon is not too strong. We strongly criticize the procedure used recently by several authors to include the final state interaction in the reactions u...

Brie y summarized, the Interaction Panel is a panel with ashing lights which generates di erent color patterns and sound/music based on user input by touching the panel or moving in the vicinity of the panel. The device is made with the intention of developing an exhibition for the Oslo Children's Museum. This report is a presentation of our results so far, and our thoughts of what the next ste...
