\section{Comparison of data and MC distributions}
|
| 2 |
\label{sec:appendix}
|
| 3 |
Here we compare data and MC distributions for data passing the
|
| 4 |
preselection requirements. In some cases, {\em e.g.} the
|
| 5 |
\met distribution, we show the ``$N-1$ plot'', {\em i.e.}, the
|
| 6 |
plot for the variable with all other kinematical cuts
|
| 7 |
applied except the cut on the variable itself. The
|
| 8 |
cut value is then indicated by a vertical red dashed line.
|

|
| 10 |
The meaning of most of the variables plotted in
|
| 11 |
the following figures should be obvious. There
|
| 12 |
are some exceptions that we exlain below
|
| 13 |
|
| 14 |
\begin{itemize}
|
| 15 |
|
| 16 |
\item $MT2$ in Figure C29 is a kinematical quantity
|
| 17 |
built from the two leptons and the \met. For events with
|
| 18 |
two $W \to \ell$ decays it should have a sharp kinematical cutoff
|
| 19 |
at $W$ mass. For more details, see Reference~\cite{ref:MT2}.
|
| 20 |
|
| 21 |
\item $MT2J$ in Figure C30 is very muck like $MT2$ but it is built
|
| 22 |
out of the leptons the \met and the two jets. For $t\bar{t}$
|
| 23 |
events it has a kinematical cutoff at $M_{\rm top}$, with tails
|
| 24 |
due to the fact that occasionally one of the $b$-jets is not
|
| 25 |
found and is replaced by a gluon jet from ISR or FSR.
|
| 26 |
For more details, see Reference~\cite{ref:MT2J}.
|
| 27 |
|
| 28 |
\item The reconstructed top mass in Figure C6 is from the
|
| 29 |
kinematical mass reconstruction of the top dilepton group.
|
| 30 |
In this case we are using the $D0$ matrix-element technique.
|
| 31 |
See Reference~\cite{ref:brown} for more details.
