The anomalous excess of low-energy nu(e) events measured in the MiniBooNE experiment is explained through a renormalization of the absolute neutrino flux and a simultaneous disappearance of the nu(e)'s in the beam, which is compatible with that indicated by the results of gallium radioactive source experiments. We present the results of the fit of MiniBooNE data (P(nu e)->nu(e) = 0.64(-0.07)(+0.08)) and the combined fit of MiniBooNE data and the nu(e) disappearance measured in the gallium radioactive source experiments, which gives P(nu e)->nu(e)=0.82 +/- 0.04. We show that our interpretation of the data is also compatible with an old indication in favor of nu(e) disappearance found from the analysis of the results of beam-dump experiments, leading to P(nu e)->nu(e)=0.80(-0.04)(+0.03).

Abstract
The anomalous excess of low-energy nu(e) events measured in the MiniBooNE experiment is explained through a renormalization of the absolute neutrino flux and a simultaneous disappearance of the nu(e)'s in the beam, which is compatible with that indicated by the results of gallium radioactive source experiments. We present the results of the fit of MiniBooNE data (P(nu e)->nu(e) = 0.64(-0.07)(+0.08)) and the combined fit of MiniBooNE data and the nu(e) disappearance measured in the gallium radioactive source experiments, which gives P(nu e)->nu(e)=0.82 +/- 0.04. We show that our interpretation of the data is also compatible with an old indication in favor of nu(e) disappearance found from the analysis of the results of beam-dump experiments, leading to P(nu e)->nu(e)=0.80(-0.04)(+0.03).Pubblicazioni consigliate
