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.

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    A unitarized FSI framework with no adjustable parameters for B decays, calibrated on BaBar γγ o D Dbar data, predicts enhanced CP asymmetries in pure-annihilation channels that match existing measurements.

    Using the measured e+e- -> gamma X(3872) cross section as a reference, the authors predict measurable e+e- -> gamma chi_c0(2P) and e+e- -> gamma chi_c2(2P) production and propose the gamma D Dbar final state as a sear...
