\section{Results for the ``edge analysis'' SUS-12-019}

The Aachen and ETH groups have reported an excess of low-mass, opposite-sign same-flavor events (see AN 2012/200 and AN 2012/231).
|
| 6 |
|
|
In App.~\ref{sec:edge_templates} we derive predictions for the Z background in the Z mass regions for the two signal regions used for this analysis,
|
| 7 |
|
|
and use these predictions to derive an estimate of the low-mass $\gamma^*$/Z contributions using an extrapolation technique
|
| 8 |
|
|
commonly referred to as the ``$R_{out/in}$'' technique.
|
| 9 |
|
|
|
| 10 |
|
|
%In App.~\ref{sec:edge_triggers} we provide a cross-check using single lepton triggers.

\subsection{Z Background Predictions for the ``Edge Analysis''}
|
| 13 |
|
|
\label{sec:edge_templates}
|
| 14 |
|
|
|
| 15 |
|
|
The two signal regions of the edge analysis are defined as:
|
| 16 |
|
|
|
| 17 |
|
|
\begin{itemize}
|
| 18 |
|
|
\item Low-\MET signal region (ETH)
|
| 19 |
|
|
\begin{itemize}
|
| 20 |
|
|
\item 2 \pt $>$ 20 GeV leptons with $|\eta|<2.4$
|
| 21 |
|
|
\item At least 3 jets (\pt\ $>$ 40 GeV, $|\eta|<3$)
|
| 22 |
|
|
\item \MET\ $>$ 100 GeV
|
| 23 |
|
|
\end{itemize}
|
| 24 |
|
|
\item High-\MET signal region (Aachen)
|
| 25 |
|
|
\begin{itemize}
|
| 26 |
|
|
\item leading lepton \pt $>$ 20 GeV, trailing lepton \pt\ $>$ 10 GeV, both with $|\eta|<2.4$
|
| 27 |
|
|
\item At least 2 jets (\pt\ $>$ 40 GeV, $|\eta|<3$) with scalar sum $H_{T}>100$~GeV
|
| 28 |
|
|
\item \MET\ $>$ 150 GeV
|
| 29 |
|
|
\end{itemize}
|
| 30 |
|
|
\end{itemize}
|
| 31 |
|
|
|

|
|
We begin with a synchronization exercise to make sure that we can reproduce the ETH/Aachen results. In Table~\ref{tab:edgesync} we
|
| 33 |
|
|
display the yields in the Z mass regions of the 2 signal regions and compare these to results from the ETH group.
|
| 34 |
|
|
In general we are synchronized to 3\% or better in all channels. Note that for the purposes of this exercise we include an additional
|
| 35 |
|
|
dimuon trigger (HLT\_Mu17\_TkMu8) which is not yet included in the results that follow. The inclusion of this trigger adds 3 $\mu\mu$
|
| 36 |
|
|
events in both the low \MET\ and high \MET\ signal regions.

In order to adapt the \MET\ templates method to predict the Z background in these regions, we make minor modifications
|
| 73 |
|
|
to the flavor-symmetric (FS) scaling factor $K$ and to the binning used for the \MET\ templates. The FS background
|
| 74 |
|
|
is estimated using e$\mu$ events in data.
|
| 75 |
|
|
To improve the precision of this background estimate, the dilepton mass requirement is not applied, and we apply a scaling
|
| 76 |
|
|
factor $K$, which is the efficiency for e$\mu$ events to fall in the Z mass window, extracted from MC.
|
| 77 |
|
|
The values of $K$ for various \MET\ intervals for the high-\MET\ region (using \pt\ $>$ (20,10) GeV leptons and at least 2 jets)
|
| 78 |
|
|
are shown in Fig.~\ref{fig:K_incl_highmet}.
|
| 79 |
|
|
Based on this plot we choose $K=0.13\pm0.02$ for \MET\ signal regions up to 200 GeV; for \MET\ 200-300 GeV and \MET\ $>$ 300 GeV
|
| 80 |
|
|
we inflate the uncertainty to $K=0.13\pm0.04$ and $K=0.13\pm0.05$, respectively, due to the limited statistical precision.
|
| 81 |
|
|
The values of $K$ for the low-\MET\ region (using \pt\ $>$ (20,20) GeV leptons and at least 3 jets) are shown in
|
| 82 |
|
|
Fig.~\ref{fig:K_incl_lowmet}.
|
| 83 |
|
|
Based on this plot we choose $K=0.14\pm0.02$ for \MET\ signal regions up to 200 GeV; for \MET\ 200-300 GeV and \MET\ $>$ 300 GeV
|
| 84 |
|
|
we inflate the uncertainty to $K=0.14\pm0.03$ and $K=0.14\pm0.07$, respectively. In addition, we change the
|
| 85 |
|
|
jet \pt\ threshold for the \MET\ templates jet multiplicity binning from 30 to 40 GeV, and change the $H_T$ bins to
|
| 86 |
|
|
(0,80,100,150,200,250,300,5000) GeV.

The strategy is to select Z$\to\ell\ell$ candidates ($81<m_{\ell\ell}<101$ GeV) with jet requirements corresponding to the
|
| 519 |
|
|
low-\MET\ and high-\MET\ signal regions, and compare the observed \MET\ distribution to the sum of the predictions from the
|
| 520 |
|
|
\zjets\ background (from the \MET\ templates method based on the \gjets\ data control sample), the flavor-symmetric background predicted
|
| 521 |
|
|
from e$\mu$ data events, and MC contributions from WZ/ZZ, as well as the rare SM processes with Z bosons ($t\bar{t}\rm{Z}$ and ZZZ, ZZW, ZWW).
|
| 522 |
|
|
|
| 523 |
|
|
The results of the low \MET\ signal region are displayed in Fig.~\ref{fig:results_lowmet} and summarized in Table~\ref{tab:results_lowmet},
|
| 524 |
|
|
separately for the Run2012A+B data (5.1 fb$^{-1}$) and Run2012C data (4.1 fb$^{-1}$).
|
| 525 |
|
|
In the Run2012A+B data, we observed a 1.6$\sigma$ excess for \MET\ $>$ 100 GeV, corresponding to the low \MET\ signal region.
|
| 526 |
|
|
However, this excess does not persist in Run2012C data, where we observe good agreement between the data and the predicted background.
|
| 527 |
|
|
In the combined Run2012A+B+C data (Fig.~\ref{fig:results_fulledge} and Table~\ref{tab:results_edgefull}) we observe reasonable
|
| 528 |
|
|
agreement over the full \MET\ range. In the \MET\ $>$ 100 GeV region we observe 288 events with a predicted background of $251\pm33$,
|
| 529 |
|
|
representing an excess of 1.0$\sigma$.
|
| 530 |
|
|
|
| 531 |
|
|
The results of the high \MET\ signal region are displayed in Fig.~\ref{fig:results_highmet} and summarized in Table~\ref{tab:results_highmet},
|
| 532 |
|
|
separately for the Run2012A+B data (5.1 fb$^{-1}$) and Run2012C data (4.1 fb$^{-1}$).
|
| 533 |
|
|
In both periods we observe good agreement between the data and predicted background over the full \MET\ range.
|
| 534 |
|
|
In the \MET\ $>$ 150 GeV region corresponding to the high \MET\ signal region in the full sample, we observe 167 events with a predicted
|
| 535 |
|
|
background of $177\pm25$ events, representing a deficit of -0.4$\sigma$.

Given a prediction for the Z background in the Z mass window, we can extrapolate to estimate the low mass $\gamma^*$/Z contribution.
|
| 906 |
|
|
We extract the ratio $R_{low/in}$ of low-mass to on-shell Z events from data,
|
| 907 |
|
|
correcting for the contribution from flavor-symmetric backgrounds, according to:
|
| 908 |
|
|
|
| 909 |
|
|
\begin{equation}
|
| 910 |
|
|
R_{low/in} = (N_{SF}^{low}-N_{OF}^{low})/(N_{SF}^{in}-N_{OF}^{in}).
|
| 911 |
|
|
\end{equation}
|
| 912 |
|
|
|
| 913 |
|
|
Here SF and OF refer to the same-flavor and opposite-flavor data yields in the ``low'' ($15<m_{\ell\ell}<70$ GeV) and ``in''
|
| 914 |
|
|
($81<m_{\ell\ell}<101$ GeV) dilepton mass regions. To predict the low-mass $\gamma^*$/Z contribution, we scale the total predicted
|
| 915 |
|
|
Z background by this quantity, which is displayed in Fig.~\ref{fig:Routin}. Here we measure $R_{low/in}$ in several \MET\ regions,
|
| 916 |
|
|
and assess the uncertainty based on the variation with respect to \MET.
|
| 917 |
|
|
Based on this plot we choose $R_{low/in}=0.08\pm0.02$ for the low \MET\ signal region and $R_{low/in}=0.13\pm0.03$ for the high \MET\ region.

We find the following results for the first 5.1 fb$^{-1}$. For the low \MET\ signal region, the total predicted Z background in the Z mass region is $39\pm9.6$
|
| 922 |
|
|
(sum of the \zjets, WZ+ZZ, and rare SM backgrounds from Table~\ref{tab:results_lowmet}, \MET\ $>$ 100 GeV region),
|
| 923 |
|
|
resulting in a $\gamma^*$/Z prediction of $3.1\pm1.1$ events.

For the high \MET\ signal region, the total predicted Z background in the Z mass region is $30\pm8.1$

(sum of the \zjets, WZ+ZZ, and rare SM backgrounds from Table~\ref{tab:results_highmet}, \MET\ $>$ 150 GeV region),

\subsection{Cross-check with single lepton triggers}

\label{sec:edge_triggers}

The nominal ``edge analysis'' is performed with dilepton triggers. An excess of SF vs. OF events may thus be observed if there
|
| 973 |
|
|
were some inefficiency for the e$\mu$ triggers used in this analysis. In this section we provide a cross-check of the nominal
|
| 974 |
|
|
analysis by including events collected with single lepton triggers. The relevant triggers are:

In the nominal analysis based on dilepton triggers only, an ee event is required to satisfy the ee dilepton trigger, a $\mu\mu$ event is required to
|
| 1000 |
|
|
satisfy one of the two $\mu\mu$ dilepton triggers, and an e$\mu$ event is required to satisfy one of the two e$\mu$ dilepton triggers. Here we compare
|
| 1001 |

Next, we compare the results obtained with the dilepton triggers to results obtained with single lepton triggers only. Since the single electron (single muon)
|
| 1050 |
|
|
triggers have \pt\ thresholds of 27 (24) GeV, we use a dilepton \pt\ $>$ (30,20) selection. The results are summarized in Table~\ref{tab:trigger2}.
|
| 1051 |
|
|
Switching from dilepton to single lepton triggers alters the yields by (-2--5)\%, and does not significantly alter the excess of SF vs. OF data yields.
