Correlations in bottom quark pair production at the Fermilab TeVatron.

摘要

I present an analysis of bb¯ pair production correlations, using dimuon-triggered data collected with the Collider Detector at Fermilab (CDF) in pp¯ collisions at s =1.96 TeV during Run II of the TeVatron. The leading order (LO) and next-to-leading order (NLO) b quark production processes are discriminated by the angular and momentum correlations between the bb¯ pair. Track-level jets containing a muon are classified by b quark content and used to estimate the momentum vector of the progenitor b quark. The theoretical distributions given by the MC NLO event generator are tested against the data.
