Abstract
The elliptic flow v_2 for strange and multi-strange bayons in 2.76 A TeV Pb+Pb collisions is investigated with VISHNU hybrid model that connects 2+1-d viscous hydrodynamics with a hadron cascade model. It is found that VISHNU nicely describes v_2(p_T) data for \Lambda, \Xi and \Omega at various centralities. Comparing with the ALICE data, it roughly reproduces the mass-ordering of v_2 among \pi, K, p, \Xi and \Omega within current statistics, but gives an inverse v_2 mass-ordering between p and \Lambda.
