Angular correlations between b jets in ${\rm p}\bar{\rm p}$ collisions at $\sqrt{s} = 1.96~ {\rm TeV}$

Abstract

We present a preliminary measurement of angular correlations between b jets. The distribution of Δϕ between a muon-tagged jet and a lifetime-tagged jet in data is compared to individual distributions for gluon splitting, flavor excitation and flavor creation [Formula: see text] processes, and background. The relative contributions of gluon splitting, flavor excitation and flavor creation to the data distribution are determined.
