Abstract
A simultaneous blast-wave fit to particle yields and elliptic flow () measured as a function of transverse momentum in Pb-Pb collisions at LHC energies is presented. A compact formula for the calculation of for an elliptic freeze-out surface is used which follows from the Cooper-Frye ansatz without further assumptions. Over the full available range, the elliptic flow data is described by the prediction based on the fit to lighter particles. This prediction shows that, due to the large mass, a sizable elliptic flow is only expected at transverse momenta above 10 GeV/.
