Nonlocal condensates and pion form factor
arXiv:0909.4624 · doi:10.1016/j.nuclphysbps.2009.12.035
Abstract
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.
