Extended Data Fig. 2: Relative contribution to \({\boldsymbol{\Lambda }}\bar{{\boldsymbol{\Lambda }}}\) hyperon pair feed-down from PYTHIA 8.2 event generator events, which are simulated through the STAR detector.
From: Measuring spin correlation between quarks during QCD confinement
The Λ and \(\bar{\Lambda }\) hyperons are selected using selection criteria from Extended Data Table 1. The pairs are divided into groups based on the origin of the single Λ (\(\bar{\Lambda }\)) hyperons in the pair: primary Λ, Λ from decay of Σ0 and Λ from decay of any other hyperon species (labelled as ‘other f.-d.’ in the axis labels).
