Observation of the χc2(2P) meson in the reaction γγ→ DD̄ at BABAR

A search for the Z(3930) resonance in γγ production of the DD̄ system has been performed using a data sample corresponding to an integrated luminosity of 384fb-1 recorded by the BABAR experiment at the PEP-II asymmetric-energy electron-positron collider. The DD̄ invariant mass distribution shows cle...
