Heavy Flavor Dynamics Across System Size At The Lhc

One of the fundamental signatures of the Quark Gluon Plasma has been the suppression of heavy flavor (specifically D mesons), which has been measured via the nuclear modification factor, R-AA and azimuthal anisotropies, v(n), in large systems. However, multiple competing models can reproduce the same data for R-AA to v(n). In this talk we break down the competing effects that conspire together to successfully reproduce R-AA and v(n) in experimental data using Trento+v-USPhydro+DAB-MOD. Then using our best fit model we make predictions for R-AA and v(n) across system size for (PbPb)-Pb-208, (129) XeXe, (ArAr)-Ar-40, and (OO)-O-16 collisions. We find that 0-10% centrality has a non-trivial interplay between the system size and eccentricities such that system size effects are masked in v(2) whereas in 30-50% centrality the eccentricities are approximately constant across system size and, therefore, is a better centrality class to study D meson dynamics across system size.
