Abstract: Exclusive meson photoproduction off deuteron is a powerful tool to study poorly known aspects of the strong interaction that are difficult to access experimentally by other means. Final-­‐state interactions in Λ and J/ψ productions allow access the dynamics of the ΛN and J/ψN elastic scattering, respectively, and provide a method of studying the properties of the Λ-­‐nucleon and the J/ψ-­‐nucleon interactions. High luminosity and high beam polarization in such experiments permit to not only determine the values of experimental observables for free-­‐neutron  target  from  data  for  a  bound-­‐neutron  target,  but  also  to  directly  probe  high-­‐ momentum nucleons in the deuteron.

In this talk we will show preliminary results for new experimental observables and techniques from our hyperon studies, obtained from data taken  with  the  CEBAF  Large  Acceptance  Spectrometer  (CLAS)  at  Jefferson  Lab  in  the  E06-­‐ 103 experiment of the 6-­‐GeV era. We will also discuss the perspectives for J/ψ studies with CLAS12 in the ongoing E12-­‐11-­‐003B experiment of the 12-­‐GeV era.
