Abstract
We present a measurement of the cross section for $W$-boson production in association with jets in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. The analysis uses a data sample corresponding to an integrated luminosity of $320\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ collected with the CDF II detector. $W$ bosons are identified in their electron decay channel and jets are reconstructed using a cone algorithm. For each $W+\ensuremath{\ge}n\mathrm{\text{\ensuremath{-}}}\mathrm{\text{jet}}$ sample ($n=1\ensuremath{-}4$) we measure the differential cross section $d\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}W+\ensuremath{\ge}n\mathrm{\text{\ensuremath{-}}}\mathrm{\text{jet}})/d{E}_{T}^{\mathrm{nth}\mathrm{\text{\ensuremath{-}}}\mathrm{jet}}\ifmmode\times\else\texttimes\fi{}\mathcal{B}(W\ensuremath{\rightarrow}e\ensuremath{\nu})$ with respect to the transverse energy ${E}_{T}$ of the $n$th-highest ${E}_{T}$ jet above 20 GeV, and the total cross section $\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}W+\ensuremath{\ge}n\mathrm{\text{\ensuremath{-}}}\mathrm{\text{jet}};{E}_{T}^{\mathrm{nth}\mathrm{\text{\ensuremath{-}}}\mathrm{jet}}>25\text{ }\text{ }\mathrm{GeV})\ifmmode\times\else\texttimes\fi{}\mathcal{B}(W\ensuremath{\rightarrow}e\ensuremath{\nu})$, for a restricted $W\ensuremath{\rightarrow}e\ensuremath{\nu}$ decay phase space. The cross sections, corrected for all detector effects, can be directly compared to particle level $W+\mathrm{\text{jet}}(\mathrm{s})$ predictions. We present here comparisons to leading order and next-to-leading order predictions.
