Measurement of ${\Xi }^{-}/{\bar{\Xi }}^{+}$ production in jets from $Z$ boson decays with the DELPHI open data

Zhouyue Fan, Yuzhi Che, Xinchou Lou +6

The production rates of ${\Xi }^{-}/{\bar{\Xi }}^{+}$ baryons in energy-ranked jets produced in $Z\to \text{hadrons}$ decays are measured using $3.2$ million hadronic $Z$ events recorded by the…
