Abstract

We show that the analysis of v0(pT) is biased when low-pT particles are not detected. The low-pT threshold shifts v0(pT) 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 v0(pT) in Pb+Pb collisions.
