We present a measurement of the correlated bb̅ 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 742  pb-1. We utilize muon pairs with invariant mass 5≤mμμ≤80  GeV/c2 produced by bb̅ double semileptonic decays. For muons with pT≥3  GeV/c and |η|≤0.7, that are produced by b and b̅ quarks with pT≥2  GeV/c and |y|≤1.3, we measure σbμ,b̅ →μ=1549±133  pb. We compare this result with theoretical predictions and previous measurements. We also report the measurement of σcμ,c̅ →μ, a by-product of the study of the background to bb̅ production.
