Measurement of B hadron angular correlations in association to a Z boson
The angular correlation between B hadrons produced in association with a $Z/\gamma^* \to \ell^+ \ell^-$, where $\ell=\rm{e}$ or $\mu$, is studied using proton-proton collisions recorded by the CMS detector at the LHC center-of-mass energy of 7 TeV. The identification of displaced secondary vertices...
