We present results from a search for {WZ} production with subsequent decay to $\ell\nu \ell'\bar{\ell'}$ $(\ell$ and $\ell'=e$ or $\mu)$ using $0.30$ fb$^{-1}$ of data collected by the D\O\ experiment between 2002 and 2004 at the Tevatron. Three events with {WZ} decay characteristics are observed. With an estimated background of $0.71\pm0.08$ events, we measure the {WZ} production cross section to be $4.5_{-2.6}^{+3.8}$~pb, with a 95\% C.L. upper limit of $13.3$~pb. The 95\% C.L. limits for anomalous {WWZ} couplings are found to be $-2.0<\Delta\kappa _{Z}<2.4$ for form factor scale $\Lambda$ = 1 TeV, and $-0.48<\lambda _{Z}<0.48$ and $-0.49<\Delta g_{1}^{Z}<0.66$ for $\Lambda$ = 1.5 TeV.

We present results from a search for {\it WZ} production with 
subsequent decay to 
$\ell\nu \ell'\bar{\ell'}$ $(\ell$ and $\ell'=e$ or $\mu)$ using  
$0.30$ fb$^{-1}$ of data collected by the D\O\ experiment between
2002 and 2004 at the Tevatron. 
Three events with {\it WZ} decay characteristics are observed.
With an estimated background of $0.71\pm0.08$ events, 
we measure the {\it WZ} production cross 
section to be $4.5_{-2.6}^{+3.8}$~\textrm{pb}, with 
a 95\% C.L. upper limit of 
$13.3$~\textrm{pb}.  
The 95\% C.L. limits for anomalous {\it WWZ} couplings
are found to be $-2.0<\Delta\kappa _{Z}<2.4$ for form factor scale 
$\Lambda$ = 1 TeV, and $-0.48<\lambda _{Z}<0.48$ and 
$-0.49<\Delta g_{1}^{Z}<0.66$ for $\Lambda$ = 1.5 TeV.

The $SU(2)_{L}\otimes U(1)_{Y}$ structure of the standard model (SM) 
Lagrangian implies that the electroweak gauge bosons 
$W$ and $Z$ interact with one another through trilinear 
and quartic vertices. As a consequence,
the production cross section $\sigma(p\bar{p}\rightarrow{\it WZ})$ depends
on the {\it WWZ} gauge coupling shown in Fig.~\ref{fig:diag}a. 
The SM predicts that the strength of that coupling is $-e\cot{\theta_W}$, 
where $e$ is the electric charge and $\theta_W$ is the weak mixing angle.
More generally, excursions of the {\it WWZ} interactions from the SM can
be described by an effective Lagrangian with parameters $g_{1}^{Z}\ $, 
$\lambda_{Z}\ $ and $\kappa_{Z}$~\cite{ref:bysm}. This effective
Lagrangian reduces to the SM Lagrangian when the couplings are set to their 
SM values $g_{1}^{Z}=\kappa_{Z}=1$ and $ \lambda_{Z}=0$.  
Non-SM values of these couplings will increase $\sigma_{\it WZ}$.  
Therefore a measurement of the {\it WZ}
production cross section provides a sensitive test of the strength of 
the {\it WWZ} interaction. 
This test also probes for low-energy manifestations of new physics, 
appearing at a 
higher mass scale, that complements searches to be carried out with future 
higher-energy accelerators.

 collisions. Diagram (a) contains the {\it WWZ} trilinear gauge 
 coupling vertex.}

\end{figure}

A model-independent test for anomalous trilinear boson couplings using 
$\sigma_{\it WZ}$ is unique among vector boson pair production processes 
in that {\it WZ} diagrams contain only {\it WWZ}, and 
not $WW\gamma$, vertices. 
Anomalous trilinear gauge boson coupling limits set using
characteristics of $W^+W^-$ 
production~\cite{CDF1, aleph, delphi, L3, opal, LEPass, run1wz}
are sensitive to both the $WW\gamma$ and {\it WWZ} couplings
and must make an assumption~\cite{LEPass, HISZ} relating them. 
Furthermore, as the $W^{\pm}Z$ production process is 
unavailable at $e^+ e^-$ colliders~\cite{aleph, delphi, L3, opal},
a hadron collider such as the Tevatron at Fermilab 
provides an unique opportunity 
for measurement of the {\it WWZ} coupling.


Using 90 pb$^{-1}$ of $p\bar{p}$ collisions collected at
$\sqrt{s}=1.8$ TeV during Run~I (1992--1996), the D\O \ Collaboration
established that 
$\sigma_{\it WZ}<47$~\textrm{pb} at 95\% C.L. From these data, D\O\ also set 
95\% C.L. limits $|g_{1}^{Z}-1|<1.63$ and $|\lambda_{Z}|<1.42$ for 
a form factor scale~\cite{ref:bysm} $\Lambda$ = 1 TeV~\cite{run1wz}. 
With a higher center-of-mass energy ($\sqrt{s}$ =1.96 \textrm{TeV}) 
expected to increase the SM {\it WZ} production cross section 
to 3.7$\pm$0.1 \textrm{pb}~\cite{ref:wzxsec}, more
luminosity, and improved detectors, the Run~II Tevatron program 
opens a new window for studies of {\it WZ} production. 
The CDF Collaboration recently announced
a $15.2$ pb upper limit at the 95\% C.L. on the combined cross section for 
{\it WZ} and {\it ZZ} production~\cite{ref:CDFZZWZ} .

We present the results of a search for {\it WZ} production with
``trilepton'' final states 
$\ell\nu \ell'\bar{\ell'}$ $(\ell$ and $\ell'=e$ or $\mu)$ 
using data collected by the D\O\ experiment from 2002--2004 
at $\sqrt{s}=1.96$ TeV. Requiring three isolated high
transverse momentum $(p_T)$ charged leptons and large missing
transverse energy
(\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$}), 
to indicate the presence of a neutrino, strongly suppresses backgrounds
which mimic the {\it WZ} signal. However, branching ratios 
sum to only $1.5\%$ for trilepton final states 
($\mu\nu ee$, $e\nu\mu\mu$, $e\nu ee$ and 
$\mu\nu\mu\mu$).  The {\it WZ} signal that we seek is distinct but rare. 

The D\O\ detector~\cite{ref:run1det,ref:run2det} 
comprises several subdetectors 
and a trigger and data acquisition system. The central-tracking system
consists of a silicon microstrip tracker (SMT) and a central fiber tracker
(CFT) located within a 2~T superconducting solenoidal magnet. 
The SMT and CFT measure the locations of the collisions and the momenta 
of charged particles. The energies of electrons,
photons, and hadrons, and the amount of 
\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$},
is measured in three uranium/liquid-argon 
calorimeters, each housed in a separate cryostat~\cite{ref:run1det}: 
a central section (CC) covering $|\eta|\leq 1.1$
and two end calorimeters (EC) extending coverage to $|\eta|\leq 4.2$,
where $\eta$ is the pseudorapidity. 
Scintillators between the CC and EC
cryostats provide sampling of developing showers for $1.1<|\eta|<1.4$. 
A muon system~\cite{ref:run2det} resides beyond the calorimetry, 
and consists of a layer of
tracking detectors and scintillation trigger counters in front of 
1.8~T toroidal magnets, followed by two similar layers behind the toroids. 
A three level trigger and data acquisition system uses information
from the subdetectors to select $\approx$ 50~Hz of collisions for 
further ``offline'' reconstruction.

With at least three high-$p_{T}$ charged leptons in the candidate
events, the overall trigger efficiency for the {\it WZ} signal 
is nearly 100\%.
Integrated luminosities for the 
$e\nu ee$, $\mu\nu ee$, $e\nu\mu\mu$ and $\mu\nu\mu\mu$ final
states are 320 $\mathrm{pb}^{-1}$, 290 $\mathrm{pb}^{-1}$, 
280 $\mathrm{pb}^{-1}$, 
and 290 $\mathrm{pb}^{-1}$, respectively, with a common uncertainty of 
$6.5\%$~\cite{lumy}. 

Electrons from $W$ and $Z$ boson decays are identified by their 
pattern of spatially isolated energy deposition in the calorimeter and by 
the presence of a matching track in the central tracking system.  
The transverse energy of an electron, measured in the calorimeter, 
must satisfy $E_{T}$ $>$ 15 \textrm{GeV}.

A muon is identified by a pattern of hits in the scintillation
counter and drift chamber system and must have a matching
central track. Muon isolation is determined from an
examination of the energy in calorimeter cells and the
momenta of any additional tracks around the muon.
Muons must have $p_{T}>15$~\textrm{\ GeV/$c$}.

Missing transverse energy
%(\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$}) 
is determined from the negative of the vector sum of transverse
energies of the calorimeter cells, adjusted for the 
presence of any muons identified above. 

The {\it WZ} event selection requires at least three charged leptons 
that originate from a common interaction vertex and survive
the electron or muon identification criteria outlined above. 
To associate reconstructed tracks with leptons unambiguously, they
are required to be spatially separated.
To select $Z$ bosons and suppress backgrounds further, the invariant mass of
a like-flavor lepton pair must fall within 
$71$ \textrm{GeV}/$c^2$ to 111 \textrm{GeV}/$c^2$ for 
$e^{+}e^{-}$ events, and 51 \textrm{GeV}/$c^2$ to 131 \textrm{GeV}/$c^2$ for 
$\mu^{+}\mu^{-}$ events, where the different mass windows correspond
to the respective resolutions of the calorimeter and the central tracker. 
For the $e\nu ee$ and $\mu\nu\mu\mu$ channels, the lepton pair with 
invariant mass
closest to the $Z$ boson mass is chosen as the $Z$ candidate. The 
\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$} is required to 
be greater than $20$ GeV, consistent with a $W$ boson decay. 
The transverse mass, although not used as a selection criterion, 
is calculated from the $p_{T}$ of the unpaired third lepton
and the \mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$}.
Finally, to reject background from $t\bar{t}$ events, the vector sum of the
transverse energies in all calorimeter cells, excluding the leptons, must be
less than 50 \textrm{GeV}. 
Figure~\ref{fig:massmet} shows the comparison of 
the dilepton invariant mass and 
\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$} 
distributions expected for $WZ\rightarrow \mu\nu\mu\mu$ events
to the background from $Z+{\rm jet(s)}$ events.

candidates are indicated as stars. The corresponding figures

Applying all selection requirements leaves one $e\nu ee$ and two 
$\mu\nu\mu\mu$ candidates. Table~\ref{tab:wzcand} summarizes the 
kinematic properties of these events.

Signal acceptances include geometric and kinematic effects and are 
obtained using
Monte Carlo samples produced with the {\sc PYTHIA} event generator 
\cite{ref:pythia} followed by the {\sc GEANT}-based~\cite{ref:geant} 
D\O\ detector-simulation program.  Acceptances are calculated by counting
the number of events that pass all selection criteria, except the lepton
identification and track-matching requirements. The results are 
$0.283\pm0.009$, $0.279\pm0.008$, $0.287\pm0.009$ and $0.294\pm0.008$ for 
$e\nu ee$, $\mu\nu ee$, $e\nu\mu\mu$ and $\mu\nu\mu\mu$ final states,
respectively.

Lepton-identification and central-track-matching efficiencies are
estimated using samples of $Z\rightarrow e^{+}e^{-}$ and 
$Z\rightarrow\mu^{+}\mu^{-}$ events.
One of the leptons from the $Z$ boson decay is required to pass all
lepton selection requirements. The other lepton is tested as to
whether it passes the selection criteria.
Both identification efficiencies and track-matching efficiencies are
determined as functions of $p_{T}$ and $\eta$. Average identification 
efficiencies are $0.929\pm0.013$ and $0.965\pm0.008$ for CC and EC
electrons, respectively, and $0.940\pm0.002$ for muons. 
Track-matching efficiencies are $0.817\pm0.002$ 
for CC electrons, $0.674\pm0.006$ for EC electrons, and $0.950\pm0.002$
for muons.  These efficiencies are folded into the {\it WZ} MC events used for
acceptance calculations. The overall {\it WZ} acceptance 
times detection
efficiencies are (10.3$\pm$1.5)\%, (11.7$\pm$0.8)\%, (13.9$\pm$1.3)\%,
and (16.3$\pm$1.8)\% for $e\nu ee$, $\mu\nu ee$, $e\nu \mu\mu$ and 
$\mu\nu\mu\mu$, respectively.

From the SM prediction for $\sigma_{\it WZ}$ and the leptonic branching
fractions of the $W$ and $Z$ bosons~\cite{ref:epj}, we expect
0.44$\pm$0.07, 0.45$\pm$0.04, 0.53$\pm$0.06, 0.62$\pm$0.08 {\it WZ} events for 
the $e\nu ee$, $\mu\nu ee$, $e\nu \mu\mu$, and $\mu\nu\mu\mu$ final 
states, respectively. 
Quoted uncertainties include statistical and systematic contributions, 
as well as the 6.5\% uncertainty in the integrated luminosity.


Among SM processes, {\it WZ} production is the dominant 
mechanism that results in events with a  
final state that includes three isolated leptons with large transverse 
momentum and with 
large \mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$}.
The main backgrounds to {\it WZ} production come from 
$Z+X$ ($X$=hadronic jets, 
$\gamma$, or $Z$) events. In $Z +{\rm jet(s)}$ events, a jet may be 
misidentified as an additional lepton. This background is estimated from 
data as follows. Events are selected using the same criteria as for the 
{\it WZ} sample, except that the requirement of the third lepton is 
dropped. The resulting ``dilepton + jet(s)'' sample includes $ee+{\rm jets}$, 
$\mu\mu+{\rm jets}$ and $e\mu+{\rm jets}$ events. Probabilities for 
hadronic jets to mimic electrons and muons are determined, 
using multi-jet data, as a function of jet $E_{T}$ and jet $\eta$. 
Applying the misidentification probabilities to jets in the dilepton + jet(s) 
events yields the total background, estimated to be $0.35\pm0.02$ events. 
In $Z+\gamma$ events, a $\gamma $ may be converted to electrons or randomly 
match a charged-particle track in the detector causing it to be misidentified 
as an electron. This background process only contributes to the 
$e\nu\mu\mu$ and $e\nu ee$ final states. Though we have identified hundreds
of $Z+\gamma$ events~\cite{r2zg}, we found the probability for a 
photon to be misidentified as an electron is $\sim 2\%$. As these 
events do not typically have large 
\mbox{${\hbox{$E$\kern-0.6em\lower-.1ex\hbox{/}}}_T$}, the number which
mimic the {\it WZ} signal is small. We estimate it as $0.145\pm0.020$ events.
The backgrounds from {\it ZZ} and $t\bar{t}$ production 
are estimated using Monte Carlo methods to be $0.20\pm0.07$ and $0.01\pm0.01$ 
events, respectively. Other sources of background are found
to be negligible. The total background is estimated to be 
$0.71\pm0.08$ events.


The combination of expected {\it WZ} signal and 
background is consistent with having observed three {\it WZ} candidates.
The probability for a background of $0.71$ events alone to fluctuate to three
or more candidates is 3.5\%.
Following the method described in Refs.~\cite{ref:epj} 
and \cite{ref:signf}, we use a maximum likelihood technique to obtain 
$\sigma_{\it WZ}=4.5_{-2.6}^{+3.8}$ $\mathrm{pb}$ and calculate the 95\% C.L.
upper limit $\sigma _{\it WZ}<$ $13.3$~\textrm{pb }for $\sqrt{s}=1.96$ 
\textrm{TeV}.  


As $\sigma_{\it WZ}$ is consistent with the SM, we can  extract 
limits on anomalous {\it WWZ} couplings.  
Monte Carlo $WZ\rightarrow \,$trilepton events are 
generated~\cite{ref:wzgenerator} 
at each point in a two-dimensional grid of anomalous couplings. 
We used a parameterized detector simulation to model the detector response 
and applied the same selection criteria that were applied to the data to 
determine the predicted {\it WZ} signal at each grid point. These
predictions are combined with the estimated background and compared with 
the three observed trilepton candidates to construct a likelihood function 
$L$. Analyses of contours of $L$  then permits
limits to be set on $\lambda_{Z}$, $\Delta g_{1}^{Z}$ and $\Delta\kappa_{Z}$, 
both individually and in pairs, where  
$\Delta \kappa_Z \equiv \kappa_Z -1$ and 
$\Delta g_1^Z \equiv g_1^Z-1$.
Table~\ref{tab:limits} lists one-dimensional 95\%
C.L. limits on $\lambda_{Z}$, $\Delta g_{1}^{Z}$ and $\Delta\kappa_{Z}$ with 
$\Lambda=$1 TeV or $\Lambda=$1.5 TeV.  Figure~\ref{fig:countour} shows
two-dimensional 95\% C.L. contour limits for $\Lambda$ = 1.5 TeV with 
the assumption of $SU(2)_L \otimes U(1)_Y$ gauge invariance relating 
the couplings~\cite{LEPass}.  The values
of the form factors are chosen such that the coupling limit contours are
within the contours provided by $S$-matrix unitarity~\cite{ref:unitarity}.

In summary, we searched for {\it WZ} production in $p\bar{p}$ collisions at 
$\sqrt{s}=1.96$ TeV. In a sample of 0.30 fb$^{-1}$, 
three candidate events
were found with an expected background of $0.71\pm0.08$ events. The 95\% C.L. 
upper limit for the {\it WZ} cross section is $13.3$ pb. Interpreting the
candidates as a combination of {\it WZ} signal plus background,
we find $\sigma_{\it WZ}=4.5^{+3.8}_{-2.6}$ pb and
provide the first measurement of the {\it WZ} production cross
section at hadron colliders. We used the results of the search to
obtain the tightest available limits on anomalous {\it WWZ} couplings
derived from a {\it WZ} final state. Furthermore, these are the most
restrictive model-independent {\it WWZ} anomalous coupling limits 
available and represent an improvement by a factor of three over the previous 
best results~\cite{run1wz}.
