An Appraisal of Muon Neutrino Disappearance at Short Baseline

Figure 6

The double ratio of the disappearance probabilities at the near and far sites, 460 and 1600 m, respectively, by using the amplitude provided by the reactor anomaly, 0.146, and mass scales ranging from 0.1 to 5 eV2 as a function of , where “ ” is the reconstructed muon momentum in MeV/c. We apply cuts on the minimum muon path length (25 cm of range in iron) and the minimum momentum ( MeV/c). A 90% fiducial acceptance of the magnet volume and an uncorrelated 1% systematic error (from OPERA experience [57]) are also considered. Data collection corresponds to 1 year, that is, p.o.t. The error bars correspond to the statistical errors. The blue band for  eV2 is obtained by including the systematic error summed quadratically to the statistical one, the same result being obtained for the other mass scales.
