摘要
We present a measurement of the correlated b (b) over bar 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 <= m(mu mu)<= 80 GeV/c(2) produced by b (b) over bar double semileptonic decays. For muons with p(T)>= 3 GeV/c and /eta/<= 0.7, that are produced by b and (b) over bar quarks with p(T)>= 2 GeV/c and /y/<= 1.3, we measure sigma(b ->mu,)(b) over bar (->mu)=1549 +/- 133 pb. We compare this result with theoretical predictions and previous measurements. We also report the measurement of sigma(c ->mu,c over bar ->mu), a by-product of the study of the background to b(b) over bar production.
