Abstract

Inclusive K+ and exclusive K+Y photoproduction on the deuteron are investigated theoretically. Modern hyperon-nucleon forces and a recently updated kaon photoproduction operator for the γ+N→K+ + Y process are used. Sizable effects of the hyperon-nucleon final state interaction are found near the K+ ΛN and K+ΣN thresholds in the inclusive reaction. Angular distributions for the exclusive process show clear YN final state interaction effects in certain kinematic regions. Precise data especially for the inclusive process around the K+ΣN threshold would help to clarify the strength and property of the ΛN-ΣN interaction.
