Abstract

We measure the ratio of cross sections, σ(pp¯→Z+2b jets)/σ(pp¯→Z+2 jets), for associated production of a Z boson with at least two jets with transverse momentum pjetT>20  GeV and pseudorapidity |ηjet|<2.5. This measurement uses data corresponding to an integrated luminosity of 9.7  fb−1 collected by the D0 experiment in Run II of Fermilab’s Tevatron pp¯ Collider at a center-of-mass energy of 1.96 TeV. The measured integrated ratio of 0.0236±0.0032(stat)±0.0035(syst) is in agreement with predictions from next-to-leading-order perturbative QCD and the Monte Carlo event generators pythia and alpgen.
