 In Charged Current Quasi-Elastic (CCQE) interactions, the dominating interaction in the ND280 near detector, kinematics of produced lepton is enough in the reconstruction of the incoming neutrino energy.However, other types of neutrino interactions in which additional particles (pions, kaons, nucleons) were lost, may be mis-reconstructed as CCQE and introduce a bias in the reconstructed neutrino energy spectrum.Thus, it is essential to optimize the detector to be sensitive to additional particles and nuclear effects.
