| dc.description | We present measurements of the process $p\bar{p} \to WZ+X \to \ell^{\prime} ν_{\ell^{\prime}} \ell \bar{\ell}$ at $\sqrt{s}=1.96$ TeV, where $\ell$ and $\ell^{\prime}$ are electrons or muons. Using 1 fb$^{-1}$ of data from the D0 experiment, we observe 13 candidates with an expected background of $4.5\pm0.6$ events and measure a cross section $σ(WZ)=2.7^{+1.7}_{-1.3}$ pb. From the number of observed events and the $Z$ boson transverse momentum distribution, we limit the trilinear $WWZ$ gauge couplings to $-0.17 \le λ_Z \le 0.21$ $(Δκ_Z = 0)$ at the 95% C.L. for a form factor scale $Λ=2$ TeV. Further, assuming that $Δg^Z_1 = Δκ_Z$, we find $-0.12 \le Δκ_Z \le 0.29$ $(λ_Z=0)$ at the 95% C.L. These are the most restrictive limits on the $WWZ$ couplings available to date. | |
