Heavy-Quark Dynamics from $D^{0}$-Meson Anisotropy-Response Scaling Violations
A species-resolved anisotropy-response scaling framework is used to investigate heavy-quark dynamics through the elliptic ($v_2$) and triangular ($v_3$) azimuthal anisotropies of $D^0$ mesons. The independently constrained light-flavor response provides a direct null test: the transformed $D^0$ harmonics exhibit approx...
