Description
The nucleon matrix elements of the operators rs2=s+(χ)χ2s(χ) and μs=1/2χxanti sγs are estimated using dispersion theory fits to the nucleon isoscalar form factor, together with a standard treatment of φ-ω mixing and some mild assumptions on the asymptotic behavior (at large q2) of nucleon form factors. The results indicate a significant strange quark content in the nucleon. (orig.)
