Elliptic flow from final state interactions in the distorted-wave emission-function model
arXiv:0810.1550 · doi:10.1103/PhysRevC.79.024902
Abstract
The effect of final state interactions on the elliptic flow coefficient measured in relativistic heavy ion collisions is investigated within the DWEF formalism established by Miller and Cramer [Phys. Rev. Lett. 94, 102302 (2005), J. Phys. G34, 703 (2007), Phys. Rev. C78, 054905 (2008)]. It is found that the optical potential previously found to give the best fit of particle multiplicity and Hanbury Brown and Twiss radii in RHIC events has a moderate effect on the resulting elliptic flow coefficient v_2. This indicates that final state interactions should be taken into account to confidently predict v_2 to better than ~20% accuracy.
