Abstract :
The three flavor version of the Nambu–Jona–Lasinio chiral soliton model for baryons is employed to calculate the twist–2 contribution to the polarized nucleon structure function g1(x). In particular the role of the strange quark degree of freedom as a collective excitation of the chiral soliton is investigated in the context of flavor symmetry breaking. The model prediction for g1(x) refers to a low momentum scale Q02. The leading order corrections to the scale dependence is computed along the QCD evolution program allowing to compare with data from SLAC.
