Description
Measurements of azimuthal correlations of charmed mesons in high-energy heavy-ion collisions can shed light on the transport properties of the Qaurk-Gluon Plasma. The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) collected in 2014 and 2016 a large sample of Au+Au reactions at $\sqrt{s_{NN}}$ = 200 GeV making such a study possible. The sPHENIX experiment will also offer a similar opportunity in the next few years. However, such a measurement in $p$+$p$ collisions at the same energy has not been feasible so far.
To provide a baseline for the heavy-ion measurements, we report studies of the azimuthal correlations between charmed mesons in $p$+$p$ reactions using two Monte Carlo event generators, PYTHIA 8 and Herwig++. We validate the models against the available data from the STAR and CDF experiments, and compare their predictions to deliver a reliable $p$+$p$ baseline for heavy-ion collision studies. Finally, we discuss prospects for performing such measurements in $p$+$p$ collisions at RHIC.
