A significant positive $v_2$ signal from long-range azimuthal correlations is observed for all particle species in high-multiplicity pPb collisions. The measurement represents the first observation of possible long-range collectivity for open heavy flavor hadrons in small systems. The results suggest that charm quarks have a smaller $v_2$ than the lighter quarks, probably reflecting a weaker collective behavior. This effect is not seen in the larger PbPb collision system at $\\sqrt{s_{_\\mathrm{NN}}} =$ 5.02 TeV, also presented.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.83911.v1/t1","@type":"Dataset","description":"The elliptic flow, $v_{2}$, for $K^{0}_{S}$ as a function of $p_{T}$ in pPb collision at
