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: L-Lbar hyperon pair feed-down composition from PYTHIA 8 event generator events, which are simulated through the STAR detector.
