An Appraisal of Muon Neutrino Disappearance at Short Baseline

Figure 7

The estimated limits at 95% C.L. for disappearance at a Short-Baseline beam at CERN for several luminosity running periods and different beam polarities, with a two-site massive spectrometer (770 tons and 330 tons, resp.) with 90% inner fiducial volume. (a) Refers to the positive polarity beam. The continuous (dashed) lines correspond to the sensitivity limits obtained with the variable. 3 years correspond to p.o.t., 5 years to p.o.t., and 10 years to p.o.t. The exclusion limit from combined MiniBooNE and SciBooNE disappearance result at 90% C.L. from [33] is shown for comparison by the black curve in the right. (b) Refers to the negative polarity beam. Sensitivity limits are evaluated with the variable. Clearly the negative polarity run allows the contemporary analysis of the and disappearance exclusion regions thanks to the disentangling of the muon charge on an event-by-event basis. The black curve in the right shows for comparison the central value of the sensitivity at 90% C.L. from combined MiniBooNE and SciBooNE disappearance result [34].
