Observed number of events and background predictions in the b-tag and b-veto categories for the τeτhad, τμτhad and τhadτhad channels. The background predictions and uncertainties are obtained from the statistical procedure discussed in Section 7. In the τlepτhad channel, the processes other than "Jet → ℓ, τhad-vis fakes" require a true hadronically decaying τ lepton or an electron or muon misidentified as a τhad-vis. The expected signal yields for the mhmod+ scenario are shown for comparison.
