On the polarization of the nucleon sea in the meson-cloud model

We show that the meson-cloud model predicts a substantial polarization of the sea quarks of the nucleon, because of the interference of \(\pi\) and \(\rho\) exchanges. This polarization is strongly flavour-dependent. The model gives an explanation of the strong increase in the structure function \(g...

Description
Summary:We show that the meson-cloud model predicts a substantial polarization of the sea quarks of the nucleon, because of the interference of \(\pi\) and \(\rho\) exchanges. This polarization is strongly flavour-dependent. The model gives an explanation of the strong increase in the structure function \(g_1\) that has isospin I = 1 at small x.
