The rescaling is explored |
| 111 |
+ |
in Table~\ref{tab:cr1yields}, |
| 112 |
+ |
Here we compare the data and MC yields in the $M_T$ signal regions |
| 113 |
+ |
and in a looser control region. Note that the |
| 114 |
+ |
MC is normalized in the $M_T$ peak region by rescaling |
| 115 |
+ |
the \wjets\ component according to Table~\ref{tab:cr1mtsf}. |
| 116 |
+ |
|
| 117 |
+ |
We also derive data/MC scale factors. |
| 118 |
+ |
These are derived in two different ways, separately for muons and |
| 119 |
+ |
electrons and then combined, as follows; |
| 120 |
+ |
\begin{itemize} |
| 121 |
+ |
\item For first three sets of scale factors, above the triple horizontal |
| 122 |
+ |
line, we calculate the scale factor as the amount by which we would |
| 123 |
+ |
need to rescale {\bf all} MC (\wjets\ , \ttbar\ , single top, rare) in |
| 124 |
+ |
order to have data-MC agreement in the $M_T$ tail. |
| 125 |
+ |
\item For the next three set of scale factors, below the triple horizontal |
| 126 |
+ |
line, we calculate the scale factor as the amount by which we would |
| 127 |
+ |
need |
| 128 |
+ |
to scale \wjets\ keeping all other |
| 129 |
+ |
components fixed in order to have data-MC agreement in the tail. |
| 130 |
+ |
\end{itemize} |
| 131 |
+ |
\noindent The true \wjets\ scale factor is somewhere in between these |
| 132 |
+ |
two extremes. We also note that there is no statistically significant |
| 133 |
+ |
difference between the electron and muon samples. We use these data |
| 134 |
+ |
to extract a data/MC scale factor for \wjets\ which will be used to |
| 135 |
+ |
rescale the \wjets\ MC tail. This scale factor is listed in the last |
| 136 |
+ |
line of the Table, and is called $SFR_{wjets}$. It is calculated as |
| 137 |
+ |
follows. |
| 138 |
+ |
\begin{itemize} |
| 139 |
+ |
\item Separately for each signal region |
| 140 |
+ |
\item As the average of the two methods described above |
| 141 |
+ |
\item Including the statistical uncertainty |
| 142 |
+ |
\item Adding in quadrature to the uncertainty one-half of the |
| 143 |
+ |
deviation from 1.0 |
