AB  - In high-energy nuclear collisions at LHC, where a QGP might be created, the degree of thermalization at the partonic level is a key issue. Due to their large mass, heavy quarks are a powerful tool to probe thermalization. We propose to measure azimuthal correlations of heavy-quark hadrons and their decay products. Changes or even the complete absence of these initially existing azimuthal correlations in Pb−Pb collisions might indicate thermalization at the partonic level. We present studies with PYTHIA for p−p collisions at 14 TeV using the two-particle transverse momentum correlator  < ―∆p<sub>t,1</sub>―∆p<sub>t,2</sub> >  as a sensitive measure of potential changes in these azimuthal correlations. Contributions from transverse radial flow are estimated.
