Christoph Grab (the CMS Collaboration)
TL;DR
This paper measures the angular correlations between beauty and anti-beauty hadrons at 7 TeV, exploring small angular separations and comparing results with perturbative QCD predictions.
Contribution
First measurement of B-Bbar angular correlations at small angles in pp collisions at 7 TeV, testing QCD predictions in collinear regions.
Findings
Sensitivity to collinear particle emission observed.
Results compared with leading and next-to-leading order QCD calculations.
Provides new data for validating QCD models at high energies.
Abstract
Measurements of the angular correlations between beauty and anti-beauty hadrons produced in LHC pp collisions at 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.
