1.1 uid12904 1: \newpage
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}.
