# Even anisotropic-flow harmonics are from Venus, odd ones are from Mars

@inproceedings{Bachmann2022EvenAH, title={Even anisotropic-flow harmonics are from Venus, odd ones are from Mars}, author={Benedikt Bachmann and Nicolas Borghini and Nina Feld and Hendrik Roch}, year={2022} }

We test the ability of the “escape mechanism” to create the anisotropic ﬂow observed in high-energy nuclear collisions. We compare the ﬂow harmonics v n in the few-rescatterings regime from two types of transport simulations, with 2 → 2 and 2 → 0 collision kernels respectively, and from analytical calculations neglecting the gain term of the Boltzmann equation. We ﬁnd that the even ﬂow harmonics are similar in the three approaches, while the odd harmonics diﬀer signiﬁcantly.
