DESCRIPTION:In the limit when the number of colours becomes large\, the QC
 D correlators may be described through the exchange of an infinite number 
 of narrow-width resonances. In this seminar we explore the structure of th
 e couplings of the high mass states\, needed to recover the right QCD asym
 ptotic behaviour. In addition\, we study how it is possible to extract inf
 ormation for the positive q^2 regime from the euclidean amplitudes\, minim
 izing the effect of the duality violations. The descriptions in terms of r
 esonances and the Operator Product Expansion are compared with the experim
 ental data\, pointing out the coincidences and discrepancies.\n\nhttps://i
