From the analytical structure of the pion form factor to finite energy relations for QCD condensates and their values through FESRs

Finite energy relations for QCD condensates of dimensions 4 and 6 are derived on the basis of the analytical structure of the pion form factor. “Standard” values of QCD condensates do not satisfy finite energy relations, but a number of recently determined values satisfy these relations. New values of QCD condensates are determined through FESRs.
