Determination of light-flavor asymmetry in the ${\Sigma }^{\pm }$ sea by the Drell-Yan process

Abstract

We propose a flavor asymmetry in the light quark sea of ${\Sigma }^{\pm }$, which can be measured in Drell-Yan experiments using charged hyperon beams on proton and deuteron targets. Such a measurement would help to reinforce the presence of pseudoscalar mesons in a quark model of baryons.
