Description
I present our study on the effect of anisotropic escape mechanism on elliptic flow in relativistic heavy-ion collisions. We employ Beer-Lambert law to allow for the transmittance of produced hadrons in the medium and calculate the anisotropy generated due to the suppression of particles traversing through the medium. We calculate the transverse momentum dependence of elliptic flow, generated from anisotropic escape mechanism due to surface bias effects, for various centralities in 200 GeV Au+Au collisions at RHIC and 2.76 TeV Pb+Pb collisions at LHC. We shall show that the surface bias effects have a sizable contribution to the total elliptic flow observed in heavy-ion collisions indicating that the viscosity of the QCD matter, extracted from hydrodynamic simulations, may be underestimated.
