Effects of kinematic cuts on $v_0(p_T)$

Year: 2026

Type: preprint

Abstract: We show that the analysis of $v_0(p_T)$ is biased when low-$p_T$ particles are not detected. The low-$p_T$ threshold shifts $v_0(p_T)$ by a constant negative value, which depends on the threshold. We evaluate the shift using hydrodynamic simulations. Correcting for this bias significantly improves agreement between ALICE and ATLAS results for $v_0(p_T)$ in Pb+Pb collisions.
