                      2: \section{\label{sub:Results-of-the}\boldmath$b$ and \boldmath$\tau$ selections}
                      3: 
                      4: In the next step we applied the requirements of tight $\tau$- and $b$-tagging.
                      5: Table \ref{cap:btaggingandtau} shows the selection criteria that
1.2     ! uid12904    6: we applied to data and MC. The $b$-tag operating point used was TIGHT, which corresponds
        !             7: to NNbtag $>$ 0.775. In there are more than 1 tau candidate in the event then we
        !             8: choose the one with the highets $NN_{\tau}$ as the only one. Also we apply a tau-jet matching
        !             9: condition. A tau candidate is only used in the measurement if the separation between it
        !            10: and a jet is $\Delta R = \sqrt{{(\Delta \eta})^{2} + {(\Delta \phi})^{2}} > 0.5$.
1.1       uid12904   11: At this stage of the analysis we separated the events dataset we deal with into parts, 
1.2     ! uid12904   12: according to which type of $\tau$ the candidate with highest $NN_{\tau}$ belongs. 
1.1       uid12904   13: This was done primarily to separate the type 3 tau events (which are 
                     14: expected to have much higher fake rate and thus weaker $\ttbar$ cross section result) from the 
                     15: type 2 events. The separate measurement channels were later combined to get the final result 
                     16: (Section \ref{sub:xsect}). In principle, types 1 and 2 should be separated as well
                     17: but as there exists a considerable 
                     18: cross-migration between them \cite{tau-id} and type 1 is a small fraction of
1.2     ! uid12904   19: the total (10\% of type 1, 54.5\% of type 2 and 35.5\% of type 3), they were taken together in this analysis. 
1.1       uid12904   20: The topological NN used to enhance the signal content is described in section \ref{sub:NN-variables} .
                     21: 
                     22: %Table \ref{b and tau type 3} shows the same efficiencies for 
                     23: %type 3. We see that for type 3 $\tau$ candidates (which are more jet-like then other types) twice more 
                     24: %candidate events are selected due to high $\tau$ fake rate.
                     25: 
                     26: 
                     27: At this point, we used these ID algorithms to define 3 mutually exclusive and
1.2     ! uid12904   28: exhastive subsamples out of the preselected data sample:
1.1       uid12904   29: 
                     30: \begin{itemize}
1.2     ! uid12904   31: \item The {}``non-$b$-tag'' or {}``signal'' sample - The $\tau$ candidate has $NN_{\tau}>0.90$ 
        !            32: ($NN_{\tau}$ denotes the NN cut commonly applied to all taus)
        !            33: for taus types 1 and 2 and $NN_{\tau}>0.95$ for taus type 3, and at least one NN b-tag (as in Table \ref{cap:btaggingandtau}).
1.1       uid12904   34: These $NN(\tau)$ cuts were chosen based on previous studies involving hadronic decays of taus \cite{tes,higgs_tau}.
                     35: This is the sample used to extract the cross section. Jets matched to $\tau$ candidates are not $b$-tagged,
                     36: althought they still count as jets.
                     37: \item The {}``$\tau$ veto sample'' or ``loose-tight $\tau$ sample'' - Same selection, but with
                     38: $0.3<NN_{\tau}<0.7$ for all taus. $\tau$ NN lower cut of 0.3 
                     39: instead of 0.0 was chosen to bias their jet properties closer to those of tight tau candidates, 
                     40: in particular, so they have narrow showers. The upper cut is at 0.7 and not 0.95 or 0.90 to reduce signal contamination. 
1.2     ! uid12904   41: In this sample, 1400000 events were used for NN training for taus of Type 1 and 2 and 600000 events were used 
        !            42: in the case of Type 3 taus. In both cases, the rest of the samples served as QCD template.
1.1       uid12904   43: \item The {}``$b$ veto'' sample - Require exactly 0 tight $b$-tags. This is 
1.2     ! uid12904   44: the control sample used to validate of the QCD modelling method. The b veto requirement
1.1       uid12904   45: implies this sample is almost purely background.
                     46: \end{itemize}
                     47: %
                     48: 
1.2     ! uid12904   49: One extra cut applied along with the $NN_{\tau}$ 
        !            50: cut described above was the so called NNelec cut. It is meant to be applied to Type 2 taus only in order
        !            51: to reduce the probability of having these being faked by electrons. We chose a non-optimized cut of NNelec $>$ 0.9.
1.1       uid12904   52: 
                     53: As both b and $\tau$ ID is the step immediately after the preselection, the number of events available is 
1.2     ! uid12904   54: 2800000 events. As explained above 1400000 events were used for taus of Type 1 and 2 NN training 
        !            55: and 600000 for Type 3 taus NN training. Thus, there are 1400000 events available in each sample for the
        !            56: measurement in the case of Types 1 and 2 and 2200000 in the case of Type 3. Details of NN training are given
1.1       uid12904   57: in Section \ref{sub:NN-variables}.
                     58: 
                     59: 
                     60: The QCD modelling method used here is the same as used in p17 and is described in Section IXA of \cite{p17_note}.
                     61: 
                     62: The final number of events in each channel for both signal and $b$ veto samples is shown
                     63: on Tables \ref{b_and_tau_type1_2}, \ref{b_and_tau_type_3}, \ref{bveto_type1_2} and \ref{b_veto_type_3} 
                     64: (only statistical uncertainties are shown).
                     65: 
                     66: As important as determining the subsamples to be used in this analysis, a determination as precise as possible 
                     67: of both signal and electroweak contamination in the ``loose-tight $\tau$ sample'' had be done in order to 
                     68: know whether this sample is totally QCD dominated or not. 
                     69: Numbers showing the composition of such sample are shown on Tables \ref{loosetight1_2} and \ref{loosetight_3}
                     70: with their respective statistical uncertainties. From the $t\bar{t}$ content in each case we are able
                     71: estimate the signal contamination in the loose-tight sample. Such contaminations are 5.4\% 
1.2     ! uid12904   72: and 3.0\% for taus of Type 1 and 2 and Type 3 respectively when $\sigma_{t\bar{t}}$ = 7.46 pb is assumed 
1.1       uid12904   73: (Section \ref{sub:mcsample}). Likewise we see that electroweak contaminations
                     74: are 2.2\% and 0.9\%. As this is the sample used to model the QCD background
                     75: both signal and electroweak contaminations were taken into account when measuring the 
                     76: cross section in Section \ref{sub:xsect}.
