Nonlocal condensates and pion form factor
A. V. PimikovA. P. BakulevN. G. Stefanis
文献摘要
We review a nonlocal-condensate approach and its application in QCD sum rules for the spacelike electromagnetic pion form factor. It is shown that the nonlocality of the condensates is a key point to include nonperturbative contributions to the pion form factor.
