\section{Results for the ``edge analysis'' SUS-12-019}
|
| 3 |
\label{sec:edge}
|
| 4 |
|
| 5 |
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 |
|
| 32 |
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.
|
| 918 |

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 $39\pm9.6$

(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.
|
| 924 |
For the high \MET\ signal region, the total predicted Z background in the Z mass region is $30\pm8.1$
|
| 925 |
(sum of the \zjets, WZ+ZZ, and rare SM backgrounds from Table~\ref{tab:results_highmet}, \MET\ $>$ 150 GeV region),
|
| 926 |
resulting in a $\gamma^*$/Z prediction of $3.8\pm1.4$ events.
|
| 927 |
Hence we summarize the 5.1 fb$^{-1}$ results as:
|
| 928 |
|
| 929 |
\begin{itemize}
|
| 930 |
\item Low \MET\ signal region
|

\begin{itemize}

We find the following results for the full 9.2 fb$^{-1}$. For the low \MET\ signal region, the total predicted Z background in the Z mass region is $68\pm17$
|
| 945 |
(sum of the \zjets, WZ+ZZ, and rare SM backgrounds from Table~\ref{tab:results_edgefull}, \MET\ $>$ 100 GeV region),
|
| 946 |
resulting in a $\gamma^*$/Z prediction of $5.4\pm1.9$ events.
|
| 947 |
For the high \MET\ signal region, the total predicted Z background in the Z mass region is $60\pm16$
|
| 948 |
(sum of the \zjets, WZ+ZZ, and rare SM backgrounds from Table~\ref{tab:results_edgefull}, \MET\ $>$ 150 GeV region),
|
| 949 |
resulting in a $\gamma^*$/Z prediction of $7.9\pm2.7$ events.
|

Hence we summarize the 9.2 fb$^{-1}$ results as:

\subsection{Cross-check with single lepton triggers}
|
| 970 |
\label{sec:edge_triggers}
|
| 971 |
|
| 972 |
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:
|
| 975 |
|
| 976 |
\begin{itemize}
|
| 977 |
|
| 978 |
\item ee channel
|
| 979 |
\begin{itemize}
|
| 980 |
\item dilepton: {\footnotesize \verb=HLT_Ele17_CaloIdT_CaloIsoVL_TrkIdVL_TrkIsoVL_Ele8_CaloIdT_CaloIsoVL_TrkIdVL_TrkIsoVL=}
|
| 981 |
\item single lepton: \verb=HLT_Ele27_WP80=
|
| 982 |
\end{itemize}
|
| 983 |
|
| 984 |
\item $\mu\mu$ channel
|
| 985 |
\begin{itemize}
|
| 986 |
\item dilepton: \verb=HLT_Mu17_Mu8= OR \verb=HLT_Mu17_TkMu8=
|
| 987 |
\item single lepton: \verb=HLT_IsoMu24= OR \verb=HLT_IsoMu24_eta2p1=
|
| 988 |
\end{itemize}
|
| 989 |
|
| 990 |
\item $e\mu$ channel
|
| 991 |
\begin{itemize}
|
| 992 |
\item dilepton: \verb=HLT_MuX_EleY_CaloIdT_CaloIsoVL_TrkIdVL_TrkIsoVL= (X,Y=17,8 OR 8,17)
|
| 993 |
\item single lepton: \verb=HLT_Ele27_WP80= OR \verb=HLT_IsoMu24= OR \verb=HLT_IsoMu24_eta2p1=
|
| 994 |
\end{itemize}
|

|
| 996 |
\end{itemize}
|
| 997 |
|

|

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 |
the results obtained from the nominal dilepton triggers with those obtained by requiring an OR of the dilepton and single lepton triggers. In this cross-check,
|
| 1002 |
an ee event is required to satisfy the ee dilepton trigger OR single electron trigger, a $\mu\mu$ event is required to
|
| 1003 |
satisfy one of the two $\mu\mu$ dilepton triggers OR one of the two single muon triggers, and an e$\mu$ event is required to satisfy one of the two e$\mu$ dilepton triggers
|
| 1004 |
OR the single electron trigger OR the single muon trigger. The results are summarized in Table~\ref{tab:triggers}. Including the single lepton triggers increases
|
| 1005 |
the yields in the ee, $\mu\mu$ and e$\mu$ final states by (1--7)\%, and does not significantly alter the excess of SF vs. OF data yields.

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.
