Search for Muon Neutrino Disappearance in the Booster Neutrino Beam of Fermilab; Busqueda de Desaparicion de Neutrinos del Muon en el Haz de Neutrinos del Booster de Fermilab

In this work we carried out the disappearance analysis of muon neutrinos produced in the Fermilab Booster Neutrino Beam, using the data released to the public by the collaborations of the MiniBooNE and SciBooNE experiments. The calculations were made with programs in C and C++, implementing the ROOT libraries. From the analysis, using both the classical Pearson method and the Feldman and Cousins frequentist corrections, we obtained the 90\% C.L. limit for the oscillation parameters sin22θ and Δm2 in the region 0.1 ≤ Δm2 ≤ 10 eV2 using a two neutrino model. The result presented in this work is consistent with the official one, with small deviations ascribed to round-off errors in the format of the used data, as well as statistical fluctuations in the generation of fake experiments used in the Feldman and Cousins method. As the official one, our result is consistent with the null oscillation hypothesis. This work was carried out independently to the MiniBooNE and SciBooNE collaborations and its results are not official.
