Analyzed normalized $Z/ ext{γ}^*$+jet angular distributions.

Abstract

We present a summary of recent measurements of vector boson production in association with jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV with the D\O\ detector. Results of measurements of the inclusive $n$-jet cross-sections, $\sigma_{n}/\sigma_{n-1}$ ratios of $W+(n)$jet production for $n=0-4$ and the normalized n^th jet $p_T$ differential cross-section distributions, and measurement of the production cross-section (times branching fraction) ratio of $Z+b$-jet to $Z$+jet production are reported. Measurement of the normalized $Z/\gamma^*$+jet angular cross-section differential distributions are also discussed.
