Assessing the role of nuclear effects in the interpretation of the MiniBooNE low-energy anomaly

Abstract

We study the impact of the effect of multinucleon interactions in the reconstruction of the neutrino energy on the fit of the MiniBooNE data in terms of neutrino oscillations. We obtain some improvement of the fit of the MiniBooNE low-energy excess in the framework of two-neutrino oscillations and a shift of the allowed region in the sin 2 2ϑ-Δm 2 plane toward smaller values of sin 2 2ϑ and larger values of Δm 2. However, this effect is not enough to solve the problem of the appearance-disappearance tension in the global fit of short-baseline neutrino oscillation data.
