dc.descriptionWe investigate the possibility of identifying an explicit pionic component of the nucleon through measurements of polarized $Δ^{++}$ baryon fragments produced in deep-inelastic leptoproduction off polarized protons, which may help to identify the physical mechanism responsible for the breaking of the Gottfried sum rule. The pion-exchange model predicts highly correlated polarizations of the $Δ^{++}$ and target proton, in marked contrast with the competing diquark fragmentation process. Measurement of asymmetries in polarized $Λ$ production may also reveal the presence of a kaon cloud in the nucleon.
