The inclusive production cross section of Λ, Λ¯ in e+e− annihilation at a c.m. energy of 29 GeV has been measured with the time-projection-chamber detector at PEP. The average Λ, Λ¯ multiplicity has been measured to be 0.197 ± 0.012(stat.) ±0.017(syst.). Λ−Λ¯ pairs have been observed in jets for the first time, and the average number of Λ−Λ¯ pairs per event has been measured to be 0.042 ± 0.017 ± 0.014.

rivet Analysis
$\Lambda$ Production in $e^+ e^-$ Annihilation at 29-{GeV}

de la Vaissiere, C. ; Luth, V. ; Abrams, G.S. ; et al.
Phys.Rev.Lett. 54 (1985) 2071-2074, 1985.
Inspire Record 209198 DOI 10.17182/hepdata.20378

The production of Λ hyperons in e+e− annihilation has been measured as a function of their total momenta, transverse momenta, and the event thrust. The total production rate is 0.213±0.012±0.018 Λ or Λ¯ per hadronic event. The observation of correlations in rapidity and angles for events with two detected Λ decays supports fragmentation models with local baryon-number compensation.
