Fig. 4. (Color online) (Upper left) Signal efficiency vs background rejection in the different combinations of kinematic variables. (Upper right and lower) 95% CL upper limits on the signal branching ratios normalized to the Standard Model τlνν¯ one as a function of the luminosity (upper right) or of different combinations discussed in the text (lower) [19].
