Abstract

The\(\left( {\frac{{m_\pi ^4 }}{{(m_u + m_d )^2 Q^2 }}} \right)\) andOS2) corrections to the leading term of the perturbative QCD calculation of the pion electromagnetic form factor are examined numerically. Both sets of terms provide significant corrections for values ofQ2 between 1 and 15 GeV2/c2.
