K{sup 0} photoproduction on the deuteron and the extraction of the elementary amplitude

The photoproduction of K{sup 0} on the deuteron has been investigated with the inclusion of the YN and KN final-state interaction (FSI), as well as the pion-mediated process {gamma}d{yields}{pi}NN{yields}KYN. The YN rescattering effects for the inclusive cross section are found to be large in the threshold regions. Polarization observables show sizable FSI effects at larger kaon and hyperon angles. It is shown that the extraction of the elementary {gamma}N{yields}KY amplitude is possible in the quasifree scattering region where FSI effects are negligible. Furthermore, the cross sections in this region are large, indicating that measurements in this kinematic region are favored.
