Abstract A significant challenge in measurements of neutrino oscillations is reconstructing the incoming energies. While modern fully-active tracking calorimeters such as liquid argon time projection chambers principle allow measurement all final state particles above some detection threshold, undetected neutrons remain a considerable source missing energy with little to no data constraining their production rates and kinematics. We present first demonstration tagging neutrino-induced using...
