Extended Data Fig. 9: Global spin alignment measurement of ϕ and K*0 vector mesons in Au+Au collisions at 0–20% centrality.
From: Pattern of global spin alignment of ϕ and K*0 mesons in heavy-ion collisions
The solid squares and stars are results for the ϕ meson, obtained with the first-order and second-order event planes, respectively. The solid circles are results for the K*0 meson, obtained with the second-order event plane.
