Measurement of B-Bbar Angular Correlations at s 7 TeV with the CMS Experiment
Abstract
Measurements of the angular correlations between beauty and anti-beauty hadrons produced in LHC pp collisions at s=7 TeV are presented. These results probe for the first time the small angular separation region and show sensitivity to collinear particle emission. The results are compared with predictions based on perturbative QCD calculations at leading and next-to-leading order.
