Inclusive negative-hadron production from high-energyν¯-nucleus charged-current interactions

We present data on inclusive negative-hadron production from charged-current antineutrino interactions in a 21% Ne-H mixture. Inclusive single-particle distributions are presented and are shown to be insensitive to the momentum transferred to the hadron vertex. Comparisons made to inclusive data from ${\pi }^{-}p$ and ${\pi }^{-}n$ interactions indicate a close similarity between the hadrons resulting from $\pi$-nucleon and $\overline{\nu }$-nucleus interactions. The general features of the $\overline{\nu }$-nucleus data are found to be similar to those seen in $\overline{\nu }p$ interactions. This last observation implies that $\overline{\nu }p$ and $\overline{\nu }n$ interactions are similar and that nuclear effects are small.
