In ultra-relativistic heavy-ion collisions a new state of matter known as the strongly interacting quark-gluon plasma (sQGP) is produced. A key observable in the study of the sQGP is anisotropic azimuthal ow. The anisotropies are described by ow harmonics, v_n. In this thesis, bias arising from non-uniform azimuthal acceptance and the effect of ow uctuations are investigated. The main result is an analysis of the pseudorapidity (η ) dependence of v₂, v₃ and v₄ over a wide kinematic range: -3:5 < η  < 5:0 in Pb-Pb collisions at √ ^sNN = 2:76 TeV. The analysis is performed using the ALICE Forward Multiplicity Detector and Silicon Pixel Detector at the CERN Large Hadron Collider (LHC). The results are compared to other LHC experiments andprevious experiments at lower collision energies.
