Abstract:
We derive the four-point vector correlators in QCD from AdS/QCD correspondence. It is shown that meson poles are correctly reproduced. The final expression also suggests a nonzero amplitude in the limit of zero virtuality of two longitudinal photons. This fact does not mean that one can produce, absorb or scatter real longitudinal photons.
