Sažetak
Measurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in √sNN = 2.76 TeV PbPb collisions. Expressed in terms of the Fourier components of the azimuthal distribution, the n = 3–6 harmonic coefficients are presented for charged particles as a function of their transverse momentum (0.3 < pT < 8.0 GeV/c), collision centrality (0%–70%), and pseudorapidity (|η| < 2.0). The data are analyzed using the event plane, multiparticle cumulant, and Lee- Yang zeros methods, which provide different sensitivities to initial- state fluctuations. Taken together with earlier LHC measurements of elliptic flow (n = 2), the results on higher- order harmonic coefficients develop a more complete picture of the collective motion in high-energy heavy-ion collisions and shed light on the properties of the produced medium.
