Abstract
A search for the resonance in production of the system has been performed using a data sample corresponding to an integrated luminosity of recorded by the BABAR experiment at the PEP-II asymmetric-energy electron-positron collider. The invariant mass distribution shows clear evidence of the state with a significance of . We determine mass and width values of and , respectively. A decay angular analysis provides evidence that the is a tensor state with positive parity and parity (); therefore we identify the state as the meson. The value of the partial width is found to be .
