title = "Observation of Ds+ →p n{\= } and confirmation of its large branching fraction OBSERVATION of Ds+ →p n{\= } ... M. ABLIKIM et al.",
abstract = "The baryonic decay Ds+→p{\=n} is observed, and the corresponding branching fraction is measured to be (1.21±0.10±0.05)×10-3, 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 e+e- double-ring collider with a center-of-mass energy of 4.178 GeV and an integrated luminosity of 3.19 fb-1. 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 W-annihilation topology in the charmed meson decays.",
