| Abstract: The second- and third-order azimuthal anisotropy Fourier harmonics are studied in pPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 8.16 TeV over a wide range of event multiplicities. The second-order, "elliptic'' harmonic moment is obtained through four-, six-, and eight-particle correlations and the third-order, "triangular'' harmonic moment is studied using four-particle correlations. The data were collected by the CMS experiment during the 2016 LHC run. A sample of peripheral PbPb collisions at $\sqrt{s_{_{\text{NN}}}}= $ 5.02 TeV, covering a similar range of event multiplicities to the pPb results, is also analyzed. Theoretical predictions that assume a hydrodynamic evolution of the created medium with initial-state density fluctuations are compared to the experimental results. | ||
