Abstract: (Elsevier)

It is argued that the scale anomaly of QCD makes the nucleon mass more strongly dependent on the sea quark masses than the naive inference.

p: mass
pi nucleon: scattering amplitude
pi nucleon: sigma term
quantum chromodynamics: anomaly
quark: mass
quark: sea
renormalization: beta function
QUARK: SEA
RENORMALIZATION: BETA FUNCTION
