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

D0 Collaboration

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…
