The decay of the $D^{0}$ into two gamma is an example of a Flavor Changing Neutral Currents (FCNC) process.
In this note, we report results of a search for the FCNC decay of the neutral $D^{0}$ meson into two photons, $D^{0} \rightarrow \gamma \gamma$. We investigate the potential of this rare charm decay using Monte Carlo simulations in the PANDA experiment. An achievable performance for the measurement of branching fraction Br($D^{0} \rightarrow \gamma \gamma$) has been presented using double tag method in sensitivity.
