Abstract
A search for the decay of the charmed meson is presented, based on data collected at the resonance with the Mark III detector at the SLAC storage ring SPEAR. No evidence for this process is found, resulting in an upper limit on the decay branching ratio of 1.7× at the 90% confidence level.
