摘要：

We give the normalized leading asymptotic Q2 dependence of the pion form factor in quantum chromodynamics: Fπ(Q2)→Q2→±a-2fπ2bQ2n|Q2|, where fπ is the pion decay constant and b=(11-23Nf)16π2. Up to non-leading-logarithmic corrections, this is equivalent to Fπ(Q2)→Q2→±a 8παs(Q2)fπ2(-Q2). These results are obtained by solving the light-cone pion Bethe-Salpeter equation in quantum chromodynamics to leading-logarithmic accuracy. © 1979 The American Physical Society.
