| contents | The significant global spin alignment observed for $ϕ$ mesons in heavy-ion collisions has sparked intense discussions about its origin and implications. One explanation suggests that fluctuations in the strong force field may introduce strong spin correlations between strange ($s$) and anti-strange ($\bar{s}$) quarks, leading to the global spin alignment of $ϕ$ mesons. Extending this line of research, the theoretical community has proposed studying the spin correlation between $Λ$ and $\barΛ$ hyperons. In this paper, we construct experimental observables and make connections between them and the theoretical proposed quantities. |
