Production of $\Xi_{c}^{0}$ and $\Xi_{b}$ in Z decays and lifetime measurement of $\Xi_{b}$
The charmed strange baryon Xi_c^0 was searched for in the decay channel Xi_c^0 -> Xi- pi+, and the beauty strange baryon Xi_b in the inclusive channel Xi_b -> Xi- l- anti-nu X, using the 3.5 million hadronic Z events collected by the DELPHI experiment in the years 1992--1995. The Xi- was recon...
