Measurement of the elliptic anisotropy of charged particles produced in PbPb collisions at √sNN=2.76 TeV
The anisotropy of the azimuthal distributions of charged particles produced in [√ over s[subscript NN]]=2.76 TeV PbPb collisions is studied with the CMS experiment at the LHC. The elliptic anisotropy parameter, v[subscript 2], defined as the second coefficient in a Fourier expansion of the particle...

| description | The anisotropy of the azimuthal distributions of charged particles produced in [√ over s[subscript NN]]=2.76 TeV PbPb collisions is studied with the CMS experiment at the LHC. The elliptic anisotropy parameter, v[subscript 2], defined as the second coefficient in a Fourier expansion of the particle invariant yields, is extracted using the event-plane method, two- and four-particle cumulants, and Lee-Yang zeros. The anisotropy is presented as a function of transverse momentum (p[subscript T]), pseudorapidity (η) over a broad kinematic range, 0.3<p[subscript T]<20 GeV/c, |η|<2.4, and in 12 classes of collision centrality from 0 to 80%. The results are compared to those obtained at lower center-of-mass energies, and various scaling behaviors are examined. When scaled by the geometric eccentricity of the collision zone, the elliptic anisotropy is found to obey a universal scaling with the transverse particle density for different collision systems and center-of-mass energies. |
