Pseudorapidity and transverse momentum dependence of flow harmonics in p Pb and PbPb collisions
Measurements of azimuthal angular correlations are presented for high-multiplicity pPb collisions at √sNN = 5.02 TeV and peripheral PbPb collisions at √sNN = 2.76 TeV. The data used in this work were collected with the Compact Muon Solenoid (CMS) detector at the European Organization for Nuclear R...

| Summary: | Measurements of azimuthal angular correlations are presented for high-multiplicity pPb collisions at
√sNN = 5.02 TeV and peripheral PbPb collisions at √sNN = 2.76 TeV. The data used in this work were collected
with the Compact Muon Solenoid (CMS) detector at the European Organization for Nuclear Research (CERN)
Large Hadron Collider (LHC). Fourier coefficients as functions of transverse momentum and pseudorapidity
are studied using the scalar product method; four-, six-, and eight-particle cumulants; and the Lee-Yang zero
technique. The influence of event plane decorrelation is evaluated using the scalar product method and found to
account for most of the observed pseudorapidity dependence. |
