An Oxygen Target for (Anti)neutrinos

Understand

We discuss a method to obtain an effective oxygen target within a low-density detector allowing an accurate characterization of the various event topologies in $\nu (\bar \nu)$-oxygen interactions.

• Results can be of interest for long-baseline neutrino oscillation experiments utilizing water targets.
• In particular, the combination of both oxygen and hydrogen targets within the same detector can provide in-situ measurements of nuclear effects and of the (anti)neutrino flux, which are the leading sources of systematic uncertainties in long-baseline oscillation analyses.
• These measurements can also provide useful information about the nuclear modifications of bound nucleons, as well as about the isospin symmetry in nucleons and nuclei.
