| Abstract | We discuss the accuracy of the usual procedure for neutrino energy reconstruction which is based on the quasielastic kinematics. Our results are described in terms of a probability distribution for a real neutrino energy starting from the reconstructed energy. Several factors are responsible for the deviations from the reconstructed value. The main one is the multinucleon component of the neutrino-nucleus interaction which in the case of Cherenkov detectors enters as a quasielastic cross section. Our procedure is discussed in connection to the MiniBooNE and T2K excess electron events from the conversion of muonneutrinos. The result is a reshaping effect which may influence the interpretation in terms of oscillation. |
