Poster Neutrino interactions

### Description

Antineutrino interactions on correlated nucleons (often referred to as 2p2h interactions) have long been an important source of uncertainty for accelerator-based neutrino oscillation experiments. Modeling them depends upon detailed modeling of nuclear structure. They are difficult to constrain and study because one interaction outcome only differs from the morphology of quasi-elastic interactions by the presence of more than one neutron.

The MINERvA detector's neutron detection capability is leveraged to quantify the rate of multi-neutron production by antineutrinos. This work focuses on low recoil antineutrino interactions to reduce noise from final state hadrons. Requiring multiple neutrons in the final state selects a phase space that is predicted to be rich in 2p2h interactions. This data will be compared to recent models for antineutrino 2p2h interactions on our hydrocarbon scintillator.
