Description
Using results from QCD spectral sum rules (QSSR), we estimate the scalar sea quark content of the nucleon. We find N/N≤10%, while for heavy quarks the value N∝2/27HN/HQ decreases like the inverse of the quark mass. A Goldberger-Treiman-Veneziano relation gσNsub(anti N) ∝ (4/√2) MN/fσ is derived for the U(1) scalar channel (STGV). (orig.)
