Elliptic Flow in a Final State Interaction Model

Abstract

We propose a final state interaction model to describe the fixed $p_T$ suppression of the yield of particles at all values of $p_T$. We make an extension of the model to the motion in the transverse plane which introduces a dependence of the suppression on the azimuthal angle $θ_R$. We obtain values of the elliptic flow $v_{2}$ close to the experimental ones for all values of $p_T$.
