Measurement of the Ratio of Inclusive Cross Sections $\sigma (p\bar{p} \rightarrow Z+2~b~\text{jets})

A Measurement of the Ratio of Inclusive Cross Sections $\sigma(p\bar{p}\rightarrow Z+b{\rm\, Jet})/ \sigma(p\bar{p}\rightarrow Z+{\rm Jet})$ at $\sqrt{s}

The ratio of the cross section for p{bar p} interactions producing a Z boson and at least one b quark jet to the inclusive Z+jet cross section is measured using 4.2 fb−1 of p{bar p} collisions collected with the D0 detector at the Fermilab Tevatron collider at √s = 1.96 TeV. The Z → l+l− candidate events with at least one b jet are discriminated from Z+ charm and light jet(s) events by a novel technique that exploits the properties of the tracks associated to the jet. The measured ratio is 0.0193 ± 0.0027 for events having a jet with transverse momentum p{sub T} > 20 GeV and pseudorapidity.
