First observation of the decay Ds+→pn̄

First observation of the decay Ds+→pn̄

Using e+e-→Ds*-Ds+ data collected near the peak Ds production energy, Ecm=4170MeV, with the CLEO-c detector, we present the first observation of the decay Ds+→pn̄. We measure a branching fraction B(Ds+→pn̄)=(1.30±0.36-0.16+0.12)×10-3. This is the first observation of a charmed meson decaying into a...
