In this work, we investigate the reaction of $\gamma\gamma \to D\bar{D}$,taking into account the s-wave $D\bar{D}$ final state interaction. By fittingto the $D\bar{D}$ invariant mass distributions measured by the Belle and BaBarCollaborations, we obtain a good reproduction of the data by means of a$D\bar{D}$ amplitude that produces a bound $D\bar{D}$ state with $I=0$ close tothreshold. The error bands of the fits indicate, however, that more precisedata on this reaction are needed to be more assertive about the position andwidth of such state.

Analysis of the $ \boldsymbol{\gamma\gamma \to D\bar D}$ reaction and the $D\bar{D}$ bound state
