In this work, we investigate the discovery potential for Y(3940) by the photoproduction process gamma p -> Y(3940)p. The numerical result shows that the upper (lower) limit of the total cross section for gamma p -> Y(3940)p is up to the order of 1 nb (0.1 mu b). Additionally, the background analysis and the Dalitz plot relevant to the production of Y(3940) are studied. The Dalitz plot analysis of Y(3940) production indicates that the Y(3940) signal can be distinguished from the background clearly. The lower limit of the number of events of Y(3940) reaches up to 10/0.02 GeV2 for 1x10(9) collisions of gamma p by studying the invariant mass spectrum of J/Sigma omega. An experimental search for Y(3940) by the meson photoproduction is suggested.
