AbstractA measurement of the angular correlations between beauty and anti-beauty hadrons (BB) produced in pp collisions at a centre-of-mass energy of 7 TeV at the CERN LHC is presented, probing for the rst time the region of small angular separation. The B hadrons are identi ed by the presence of displaced secondary vertices from their decays. The B hadron angular separation is reconstructed from the decay vertices and the primaryinteraction vertex. The di erential BB production cross section, measured from a data sample collected by CMS and corresponding to an integrated luminosity of 3:1 pb-1, shows that a sizable fraction of the BBpairs are produced with small opening angles. These studies provide a test of QCD and further insight into the dynamics of bb production.
