Charmed-D-Meson Production by Neutrinos

Abstract

We have observed the production of the $D^0$ meson by neutrinos followed by the decay $D^0\to {K_S}^0+{\pi }^{+}+{\pi }^{-}$. Correcting for detection efficiencies and $K^0$ decay branching ratios, we find that the production of the $D^0$ followed by decay into $K^0{\pi }^{+}{\pi }^{-}$ corresponds to (0.7 ± 0.2)% of all charged-current neutrino interactions.
