rho_00 vs. pT for K*0 in pp collisions at 13 TeV and Pb-Pb collisions at 2.76 and 5.02 TeV. The Pb-Pb results are for centrality class 10-50%. The black dashed line shows the expectation for no polarization i.e. rho_00=1/3. The statistical uncertainties are shown by bars and systematic uncertainties are shown by boxes.
