Abstract
We search for decays, where indicates that the pair originates from the decay of a or . Results are based on decays collected with the BABAR detector at SLAC. We set an upper limit on the ratio (). This constrains the amplitude ratio (90% C.L.), consistent with expectations. The small value of favored by our analysis suggests that the determination of the Cabibbo-Kobayashi-Maskawa phase from will be difficult.
