The baryon mass spectrum is studied to determine the u u, d, and s contents in the nucleon. We find that higher-order symmetry-breaking terms in the mass operator are necessary to estimate p|u»u|p, p|d»d|p, and p|s»s|p in a self-consistent way. We also assess the scalar (pseudoscalar) Higgs-boson couplings to baryons. © 1992 The American Physical Society.
