Extended Data Fig. 2: Efficiency-corrected ϕ-meson yields as a function of cosθ* and corresponding fits with equation (2) in Methods.
From: Pattern of global spin alignment of ϕ and K*0 mesons in heavy-ion collisions
The red stars are efficiency-corrected yields for ϕ mesons with |y| < 1.0 and 1.2 < pT < 1.8 GeV c−1, for 20–60% centrality at \(\sqrt{{s}_{{\rm{NN}}}}=27\,{\rm{GeV}}\).
