On the polarization of sea antiquarks in the proton

We give some predictions about the magnitude of the sea antiquarks polarization in the proton. In order to get the results we use the experimental data concerning β-decay gA coupling constants and magnetic moments of octet baryons. We also show the consistency between our calculations and those made in the MIT bag model with one-gluon-exchange correction taken into account. We also quote the numbers for the polarization quantities derived in two specific plausible models. (orig.)
