Abstract

Although the analysis of the BaBar Collaboration prefers J^P=0^+ for the X(3915), it is difficult to assign the X(3915) to the \chi_{c0}(2P). We show that there is an indication of the \chi_{c0}(2P) with a mass around 3840 MeV and width of about 200 MeV in the Belle and BaBar data for \gamma \gamma --> D\bar D.
