Abstract
Measurements of the azimuthal anisotropy of charged hadrons are presented for PbPb collisions at sNN=2.76 TeV over an extended transverse momentum range. The data were collected with the CMS detector at the LHC. The anisotropy parameter (v2) is extracted up to a significantly higher pT region than previously achieved, by correlating charged tracks with respect to the event plane reconstructed using the energy deposited in forward-angle calorimeters. These new data can impose quantitative constraints on the details of in-medium parton energy loss models, particularly the influence of the path length and the shape of the interaction region.
