Figure 5.6.: Expected and observed distributions of m vis ( `, τ ) in the FRW. In the lower panel of each plot, the ratios of the observed yields to the predicted background yields are shown. The hatched error bands represent the combined statistical and systematic uncertainties. The last bin in each plot includes overflow events.
