dc.description.abstractWe study the process γγ→J/ψω using a data sample of 519.2  fb[superscript -1] recorded by the BABAR detector at SLAC at the PEP-II asymmetric-energy e[superscript +]e[superscript -] collider at center-of-mass energies near the Υ(nS) (n=2,3,4) resonances. We confirm the existence of the charmoniumlike resonance X(3915) decaying to J/ψω with a significance of 7.6 standard deviations, including systematic uncertainties, and measure its mass (3919.4±2.2±1.6)  MeV/c[superscript 2] and width (13±6±3)  MeV, where the first uncertainty is statistical and the second systematic. A spin-parity analysis supports the assignment J[superscript P]=0[superscript +] and therefore the identification of the signal as due to the χ[subscript c0](2P) resonance. In this hypothesis we determine the product between the two-photon width and the final state branching fraction to be (52±10±3)  eV.en_US
