Description
We employ a Relativistic Full Boltzmann Transport approach to investigate the emergence of universality in a wide range of collision systems, starting from a typical $pp$ setup and going up to $pA$ and $AA$ collisions. Our focus is concentrated on the attractor behaviour in the momentum moments of the distribution function and in the anisotropic flows $v_n$, with particular attention on the impact of Glasma initial correlations in momentum space on the $v_n(p_T)$ going from $pp$, to $pA$ and $AA$ collisions. We study how the interplay of the transverse system size $R$ and the mean free path $\lambda_{\text{mfp}}$ allows to define an equivalence relationship between different simulations and how their ratio compares to the well-known opacity parameter $\hat \gamma$. Finally, we show first results in the non-conformal case (finite mass) and for a temperature-dependent $\eta/s$, discussing when they imply deviations from universality.
