Abstract / Bemerkung
To assess how anisotropic transverse flow is cre-ated in a system out of equilibrium, we compare several kinetic-theoretical models in the few-rescatterings regime. We compare the flow harmonics v & bdquo; from three types of trans-port simulations, with either 2 -> 2 or 2 -> 0 collision ker-nels and in the former case allowing the particles to rescatter several times or not, and from analytical calculations neglect-ing the gain term of the Boltzmann equation. We find that the even flow harmonics are similar in all approaches, while the odd ones differ significantly. This suggests that while even v(n) harmonics may to a large extent be due to the anisotropic escape probability of particles, this is not the predominant mechanism underlying the odd v(n) coefficients.
