Results from first measurements of charged-particle differential elliptic flow, obtained in Pb+Pb collisions at {radical}(s{sub NN})=2.76 TeV with the ALICE detector at CERN's Large Hadron Collider (LHC), are compared to those obtained for Au+Au collisions at {radical}(s{sub NN})=0.2 TeV with the PHENIX detector at BNL's Relativistic Heavy Ion Collider (RHIC). The comparisons, made as a function of centrality (cent) or the number of participant pairs (N{sub part}) and particle transverse momentum p{sub T}, indicate an excellent agreement between the magnitude and trends for the flow coefficients v{sub 2}(p{sub T},cent). Analysis indicates that the averaged specific viscosity of the quark gluon plasma (QGP) produced in LHC collisions is similar to that for the strongly coupled QGP produced in RHIC collisions.
