Supporting figures:


Figure 1: 2D invariant mass of pi-p pairs, paired with pi+pbar pairs. The true L-Lbar pairs are visible as the main peak in the middle of the plot. The two ridges then correspond to a real L or Lbar matched with combinatorial background. The main peak and both ridges are on top of a continuum background that originates from background pi-p pairs paired with background pi+pbar pairs.


Figure 2: dN/dcos(theta*) distributions of decay (anti-)protons for LLbar, LL, and LbarLbar hyperon pairs measured at mid-rapidity (|y| < 1). Panel a) shows pairs with |Delta y| < 0.5 and panel b) with 0.5 < |Delta y| < 2.0. The fits to the data are used to extract the corresponding spin-spin correlation values P_L1L2.


Figure 3: dN/dcos(theta*) distributions of decay (anti-)protons for LLbar, LL, and LbarLbar hyperon pairs measured at mid-rapidity (|y| < 1). Panel a) shows pairs with |Delta phi| < pi/4 and panel b) with pi/4 < |Delta phi| < pi. The fits to the data are used to extract the corresponding spin-spin correlation values P_L1L2.


Figure 4: Spin-spin correlation P_L1L2 of LLbar, LL, and LbarLbar hyperon pairs pairs with |Delta y| < 0.5 (a)) and 0.5 < |Delta y| < 2.0 (b)). The hyperon pair P_L1L2 is compared to K0sK0s and PYTHIA baseline.


Figure 5: Spin-spin correlation P_L1L2 of LLbar, LL, and LbarLbar hyperon pairs pairs with |Delta phi| < pi/3 (a)) and pi/3 < |Delta phi| < pi (b)). The hyperon pair P_L1L2 is compared to K0sK0s and PYTHIA baseline.
