英文摘要:
A brief review on some recent progresses in our understanding of multi-quark components in baryons is presented. The multi-quark components in baryons seem to be mainly in colored quark cluster configurations rather than in "meson cloud" configurations or in the form of a sea of quark-antiquark pairs. The colored quark cluster multi-quark picture gives a natural explanation of empirical indications for a positive strangeness magnetic moment mu(s) of the proton and the longstanding mass-reverse problem of S11(1535) and P11(1440) N* resonances. A model-prediction for the mu(s) of the proton is given.
