Abstract

We analyze the reaction gamma + d --> K+ + Lambda (Sigma) + N using the Nijmegen soft core hyperon-nucleon interactions NSC97f and NSC89 and a recently updated production operator for the gamma + N --> K+ + Lambda(Sigma) processes. Significant effects of the YN final state interaction are found near both the K+ Lambda N and K+ Sigma N thresholds.
