# Measurement of correlated $b\bar{b}$ production in $p\bar{p}$ collisions at $\sqrt{s}$=1960GeV

Abstract : We present a measurement of the correlated b-bbar 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 $5 \leq m_{\mu\mu} \leq 80$ GeV/c^2 produced by b-bbar double semileptonic decays. For muons with $p_T \geq 3$ GeV/c and $|\eta| \leq 0.7$, that are produced by b and bbar quarks with $p_T \geq 2$ GeV/c and $|y| \leq 1.3$, we measure $\sigma_{b\to\mu, \bar{b}\to\mu} = 1549 \pm 133$ pb. We compare this result with theoretical predictions and previous measurements. We also report the measurement of $\sigma_{c\to\mu, \bar{c}\to\mu}$, a by-product of the study of the background to b-bbar production.
