We study the deeply virtual Compton scattering off a spin-one particle, which is exemplified by the case of coherent scattering on a deuteron target. We discuss the role of twist three contributions for restoring the QED gauge invariance of the amplitude corresponding to this process. We consider both kinematical and dynamical sources of twist three generalized parton distributions.

Original abstract
We study the deeply virtual Compton scattering off a spin-one particle, which is exemplified by the case of coherent scattering on a deuteron target. We discuss the role of twist three contributions for restoring the QED gauge invariance of the amplitude corresponding to this process. We consider both kinematical and dynamical sources of twist three generalized parton distributions.

One of the main reasons of this interest is the fact that the DVCS process gives information about a new type of parton distributions, called generalized parton distributions (GPDs) which allow to extract much information about the quark and gluon structure of hadrons, particularly its spin structure [ref] , and to allow a femtophotography of nuclei [ref] .
