Description
NOvA is a long-baseline neutrino experiment at Fermilab that studies neutrino oscillations via electron neutrino appearance and muon neutrino disappearance. The oscillation measurements compare the Far Detector data to an oscillated prediction which combines Near Detector (ND) data and the current understanding of neutrino interactions through simulation using GENIE. By adjusting the cross section model to better represent neutrino scattering data from NOvA’s ND and other experiments, we can extract oscillation parameters with more accurate cross section uncertainties. The adjustments are performed using the ND data and simulation, before oscillations occur. We describe the tuning made to GENIE, particularly to the 2p2h and FSI models, and the construction of the associated uncertainties.
