The production and decay of beauty baryons (b-baryons) have been studied using 1.7 \times 10^6 Z hadronic decays collected by the DELPHI detector at LEP. Three different techniques were used to...

Strange baryon production in Z hadronic decays (1995)

Abreu, P, Adam, W, Adye, T, Agasi, E, Ajinenko, I, Aleksan, Roy, ...

A study of the production of strange octet and decuplet baryons in hadronic decays of the Z recorded by the DELPHI detector at LEP is presented. This includes the first measurement of the \Sigma^\pm...
