In the (1+1)-dimensional soliton model, the self-consistent coupled equations of motion are formulated making use of time-dependent variational procedure with the aid of canonicity conditions developed in the time-dependent Hartree-Fock theory.

The sea-quark content of baryons (such as s^^-s, c^^-s, b^^-b・・・) is calculated by a combined use of the QCD trace anomary and a chiral quark model. The result is applied to the examination of the explicit symmetry breaking in baryons (such as the π-N and K-N sigma terms), the intrinsic heavy quqrks in baryons, and the Higgs-baryon coupling constants. We find that (i) the large s^^-s content is unnecessary to reproduce the empirical value of the sigma term, (ii) the probability of finding charm in the nucleon os about 0.5%, which is relevant to the charm structure function of the nucleon at large x and also to the chram production in proton-nucleous collisions at large Feynman x_F, and (iii) both strange and heavy quarks are equally important for the Higgs-nucleon coupling. Small but non-negligible OZI-violation in baryons due to the axial anomaly plays a key role in all the above quantites. The sea-quark content of the pion and the kaon and the color-sextet quarkbcontent in nucleon are also discussed.

The baryon-number-one soliton solution of a chiral quark lagrangian is obtained numerically in the mean-field approximation with full inclusion of the Dirac sea quarks using the proper-time regularization. The collective quantization method is applied to this static solution to obtain the nucleon (and Δ) state with the definite spin and isospin. We then evaluate various nucleon observables in a nonperturbative manner with inclusion of the vacuum polarization effects. The proton spin analysis is shown to be particularly useful for clarifying the underlying dynamical content of the Skyrme model at quark level.
