The Quark Distributions of Baryons

Abstract

The recent progress in the investigations on the quark structure of the $Λ$ and $Σ$ baryons are reviewed. It is shown that the quark structure of $Λ$ and $Σ$ hyperons can provide a new domain to test various theories concerning the spin and flavor structure of the nucleon. The $Λ$ and $Σ$ Physics might be new directions to explore the quark distributions of baryons both theoretically and experimentally.
