Abstract
It is shown that the principal pattern in baryon spectroscopy, which is ass ociated with the flavor-spin hyperfine interactions, is due to the spontane ous breaking of chiral symmetry in QCD and persists in the chiral limit. Al l corrections, which are associated with a finite quark (Goldstone boson) m ass are suppressed by the factor( mu/Lambda(chi))(2) and higher. (C) 1999 P ublished by Elsevier Science B.V.
