Goldberger-Treiman discrepancy and the momentum variation of the pion-nucleon form factor and pion decay constant

We suggest that the observed 6% Goldberger-Treiman discrepancy is due in part to a 3% variation in the pionnucleon form factor and in part due to a 3% variation in the pion decay form factor from q²=m_π^_² to q²=0.NUCLEAR REACTIONS Goldberger-Treiman discrepancy, πNN form factor, pion decay form factor, chiral symmetry breaking, current quark masses.
