Heavy flavor dynamics across system size at the LHC
Abstract
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, RAA and azimuthal anisotropies, vn, in large systems. However, multiple competing models can reproduce the same data for RAA to vn. In this talk we break down the competing effects that conspire together to successfully reproduce RAA and vn in experimental data using Trento+v-USPhydro+DAB-MOD. Then using our best fit model we make predictions for RAA and vn across system size for 208PbPb, 129XeXe, 40ArAr, and 16OO 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 v2 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.
