Table 1: Number of ℓ +τ candidates for Monte Carlo samples and data. tt(ℓ+e) are tt events with one identified lepton and an electron reconstructed as a τ candidate.
Figure 1 shows the BDT j (OS-SS) distributions of ℓ+τ events with 0 b-tag and the 0 b-tag background template after  subtract-ing the expected number of τ leptons and applying the MC  cor-rections
