Measurement of correlated bb̄ production in pp̄ collisions at s=1960GeV
2008
We present a measurement of the correlated bb 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{sup -1}. We utilize muon pairs with invariant mass 5{ =}3 GeV/c and |{eta}|{ =}2 GeV/c and |y|{<=}1.3, we measure {sigma}{sub b{r_reversible}}{sub {mu}}{sub ,b{r_reversible}}{sub {mu}}=1549{+-}133 pb. We compare this result with theoretical predictions and previous measurements. We also report the measurement of {sigma}{sub c{r_reversible}}{sub {mu}}{sub ,c{r_reversible}}{sub {mu}}, a by-product of the study of the background to bb production.
