### Description

Measurements of long-range azimuthal correlations involving heavy-flavor quarks provide a powerful tool in unraveling the origin of collectivity observed in small collision systems. With data collected by the CMS experiment at the LHC in 2016, elliptic azimuthal anisotropy ($v_2$) of prompt $D^{0}$ meson at mid-rapidity in 8.16 TeV pPb collisions is presented from long-range two-particle correlations over a wide transverse momentum range. Results for light-flavor strange hadrons, including $K_{S}^{0}$, $\Lambda$, $\Xi^{-}$ and $\Omega^{-}$ are also presented in both pPb and PbPb collisions. Divided by the number of constituent quarks (NCQ), the NCQ scaling relation of $v_2$ among heavy and various light flavor species is tested. The result reveals key insights to heavy quark collectivity developed in high-multiplicity pPb systems.
