Highlights

= 2.76 and 5.02 TeV shown in Figs. 3–5 and Table II are updated with the opposite sign
Neither of the changes above alter the conclusion of the published paper, that the average and polarization for the 15–50% centrality range at the two collision energies is consistent with zero, PH (%) ≈ −0.01 ± 0.05(stat.) ± 0.03(syst.)
The systematic uncertainties are shown as shaded boxes

Summary

Introduction

(Received 26 September 2021; published 8 February 2022) The correct version of Eq (3) in the paper for PH is ΑH is the / decay parameter, RP is the reaction plane angle, and φp∗ is the azimuthal angle of the decay proton’s momentum in the rest frame.
