We will present a review of selected results on strange baryon production from nucleus-nucleus collisions at the AGS, SPS and RHIC. From the AGS and SPS heavy ion physics program several intriguing aspects: centrality dependence of strangeness production, anti-hyperon yield, hyperon production enhancement and baryon number transport will be highlighted. Our discussion on RHIC results will focus...

When we model the way that particles are produced from e+e− interactions it is a common assumption that the mode through which fragmentation leads to particle production in one hemisphere occurs largely independently of particle production in the opposite hemisphere. In this paper we will present our measurements of the correlated production of the Λc baryon. Through our studies of the Λc baryo...

Leptogenesis constitues a very simple scenario to achieve the baryon asymmetry that we observe today. It requires only the presence of right handed neutrinos (which arise very naturally in many extensions of the Standard Model) and depends crucially on the mechanism responsible for their production. In particular, when their mass exceeds the inflaton mass (10 GeV in chaotic inflation) only non ...

We report on several studies of charm baryon production and decays by the BABAR collaboration. We confirm previous observations of the Ξ ′ 0/+ c , Ξ c (2980) + and Ξ c (3077) + baryons, measure branching ratios for Cabibbo-suppressed Λ + c decays and use baryon decays to study the properties of the light-quark baryons, Ω − and Ξ(1690) 0 .
