Query: Hard exclusive photoproduction of charmed mesons   {We investigate the photoproduction process $ p \gamma \rightarrow
\Lambda_{c}^{+} \overline{D^{0}}$ within the handbag approach, which we assume
to be the dominant mechanism at energies well above the production threshold
and in the forward scattering hemisphere.
