Abstract
A narrow state, which we label with a mass is observed in the inclusive mass distribution in of annihilation data recorded by the BABAR detector at the SLAC PEP-II asymmetric-energy storage ring. The observed width is consistent with the experimental resolution. The data favor decay through rather than through An analysis of data accounting for the influence of the produces a mass of
