Abstract
The baryonic decay is observed, and the corresponding branching fraction is measured to be , where the first uncertainty is statistical and second systematic. The data sample used in this analysis was collected with the BESIII detector operating at the BEPCII double-ring collider with a center-of-mass energy of 4.178 GeV and an integrated luminosity of . The result confirms the previous measurement by the CLEO Collaboration and is of greatly improved precision. This result will improve our understanding of the dynamical enhancement of the -annihilation topology in the charmed meson decays.
