Abstract

Hydrodynamic simulations are used to make predictions for the integrated elliptic flow coefficient v₂ in √(s)=5.5 TeV lead-lead and √(s)=14 TeV proton-proton collisions at the LHC. We predict a 10% increase in v₂ from RHIC to Pb+Pb at LHC, and v₂\ensuremath∼0 in p+p collisions unless \ensuremathη/s<0.08.
