Inclusive $K^{+}$ and exclusive $K^{+}Y$ photoproduction on the deuteron: $\Lambda$- and $\Sigma$-threshold phenomena

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 $\gamma +N\to K^{+}+Y$ process are used. Sizable effects of the hyperon-nucleon final state interaction are found near the $K^{+}\Lambda N$ and $K^{+}\Sigma N$ 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 $K^{+}\Sigma N$ threshold would help to clarify the strength and property of the $\Lambda N-\Sigma N$ interaction.
