This study measures the $\\Xi^{-}/\\bar{\\Xi}^{+}$ production rates and momentum spectra in energy-ranked jets using 3.2 million $Z\\to\\text{hadrons}$ events from the DELPHI open data collected from 1992 to 1995. Jets are reconstructed with the Durham algorithm with $y_{\\text{cut}}=0.005$, and quark- and gluon-enriched jet samples are obtained from the energy ordering of jets in three-jet events.
