Correlation and flow phenomena in pPb and PbPb at CMS

Recent measurements of correlation and flow phenomena in pPb and PbPb collisions from the CMS experiment are presented. Higher-order flow Fourier harmonics (vnvn) are systematically studied in PbPb collisions using various methods. Flow phenomena in the most violent collisions at the LHC are also studied including the ultra-central PbPb collisions and very high-multiplicity pPb collisions.
