Abstract. The large and saturating differential elliptic flow v 2 (p ⊥ ) observed in Au + Au reactions at RHIC so far could only be explained assuming an order of magnitude denser initial parton system than estimated from perturbative QCD. Hadronization via parton coalescence can resolve this "opacity puzzle" because it enhances hadron elliptic flow at large p ⊥ relative to that of partons at the same transverse momentum. An experimentally testable consequence of the coalescence scenario is that v 2 (p ⊥ ) saturates at about 50% higher values for baryons than for mesons. In addition, if strange quarks have weaker flow than light quarks, hadron v 2 at high p ⊥ decreases with relative strangeness content.

“…Covariant parton transport theory [3,14,15,16,17,18] overcomes this problem via replacing the assumption of local equilibrium by that of a finite local mean free path λ(s, x) ≡ 1/σ(s)n(x). The theory then naturally interpolates between free streaming (λ = ∞) and ideal hydrodynamics (λ = 0).…”

We show that hadronization via quark coalescence enhances hadron elliptic flow at large p ⊥ relative to that of partons at the same transverse momentum. Therefore, compared to earlier results based on covariant parton transport theory, more moderate initial parton densities dN/dη(b = 0) ∼ 1500 − 3000 can explain the differential elliptic flow v2(p ⊥ ) data for Au + Au reactions at √ s = 130 and 200A GeV from RHIC. In addition, v2(p ⊥ ) could saturate at about 50% higher values for baryons than for mesons. If strange quarks have weaker flow than light quarks, hadron v2 at high p ⊥ decreases with relative strangeness content.

“…Eq. (2) could in principle be extended for bosons and/or for inelastic processes, such as gg ↔ ggg [31,32]. However, with the new nonlinearities these extensions introduce, it is very challenging to maintain Lorentz covariance numerically at opacities expected at RHIC.…”
