Measurement of correlated bb̄ production in pp̄ collisions at s=1960GeV

Published

Journal Article

We present a measurement of the correlated bb̄ production cross section. The data used in this analysis were taken with the upgraded CDF detector (CDF II) at the Fermilab Tevatron collider, and correspond to an integrated luminosity of 742pb-1. We utilize muon pairs with invariant mass 5≤mμμ≤80GeV/c2 produced by bb̄ double semileptonic decays. For muons with pT ≥3GeV/c and |η|≤0.7, that are produced by b and b̄ quarks with pT ≥2GeV/c and |y|≤1.3, we measure σb→μ, b̄→μ=1549±133pb. We compare this result with theoretical predictions and previous measurements. We also report the measurement of σc→μ,c̄→μ, a by-product of the study of the background to bb̄ production. © 2008 The American Physical Society.
