Abstract

CERN-LHC. We present measurements of the elliptic ($\mathrm{v}_2$), triangular ($\mathrm{v}_3$) and quadrangular ($\mathrm{v}_4$) anisotropic azimuthal flow over a wide range of pseudorapidities ($-3.5< \eta < 5$). The measurements are performed with Pb-Pb collisions at sqrtstextNN=2.76\sqrt{s_{\text{NN}}} = 2.76sqrtstextNN=2.76 TeV using the ALICE detector at the Large Hadron Collider (LHC). The flow harmonics are obtained using two- and four-particle correlations from nine different centrality intervals covering central to peripheral collisions. We find that the shape of mathrmvn(eta)\mathrm{v}_n(\eta)mathrmvn(eta) is largely independent of centrality for the flow harmonics n=2−4n=2-4n=2−4, however the higher harmonics fall off more steeply with increasing ∣eta∣|\eta|∣eta∣. We assess the validity of extended longitudinal scaling of mathrmv_2\mathrm{v}_2mathrmv_2 by comparing to lower energy measurements, and find that the higher harmonic flow coefficients are proportional to the charged particle densities at larger pseudorapidities. Finally, we compare our me...
