Cross Section Measurements with the Accelerator Neutrino Neutron Interaction Experiment

The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton gadolinium-doped water Cherenkov detector on-axis at the Booster Neutrino Beam (BNB) at Fermilab. ANNIE's experimental goals include cross section and neutron multiplicity measurements of neutrino-nucleus interactions in water, and test new detector technologies. Among the cross section measurements, the experiment seeks to measure CC Inclusive and CC0pi cross sections which are relevant toward oscillation experiments. These measurements may be used in a joint analysis with Liquid Argon Time Projection Chamber (LArTPC) experiments, such as MicroBooNE and SBND, also on the BNB line for multi-nuclear-target measurements. This would provide unique constraints on nuclear modeling relevant to next generation liquid argon experiments.
