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 $p_T$.4 pages, 6 figures, proceedings of XLIst Rencontres de Moriond: QCD and Hadronic Interactions at high energyHigh Energy Physics - Phenomenologytext
