Abstract
We present measurements of the decays and with . The data sample used, collected with the BABAR detector at the PEP-II asymmetric-energy storage ring, corresponds to pairs. Branching fraction measurements of and are obtained. We set an upper limit on the natural width of the of at the 90% confidence level.
