Measurement of the ratio of inclusive cross sections $\sigma (p\bar{p}\to Z+2b\text{jets})/\sigma (p\bar{p}\to Z+\text{2 jets})$ in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV

Abstract

We measure the ratio of cross sections, $\sigma (p\bar{p}\to Z+2b\text{jets})$/$\sigma (p\bar{p}\to Z+\text{2 jets})$, for associated production of a $Z$ boson with at least two jets with transverse momentum $p_T^{\mathrm{jet}}>20$ GeV and pseudorapidity $|{\eta }^{\mathrm{jet}}|<2.5$. This measurement uses data corresponding to an integrated luminosity of 9.7 fb${}^{-1}$ collected by the \DO experiment in Run II of Fermilab's Tevatron \ppbar Collider at a center-of-mass energy of 1.96 TeV. The measured integrated ratio of $0.0236\pm0.0032\left(\mbox{stat}\right)\pm0.0035\left(\mbox{syst}\right)$ is in agreement with predictions from next-to-leading-order perturbative QCD and the Monte Carlo event generators {\sc pythia} and {\sc alpgen}.
