Possibilities of observing a signal of an bound state are investigated by considering photoproductions of the and mesons on a deuteron target with forward proton emission. By using effective models for the and amplitudes, we calculate photoproduction cross sections of the bound state. As a result, we find that the signal of the bound state can be seen below the threshold in the invariant mass spectrum.
