Description
We find an asymptotic solution in the ultraviolet for lower-spin two-, three- and multi-point correlators and S-matrix amplitudes in large-N QCD (and in n=1 SUSY QCD) in terms of glueball and meson propagators (and their SUSY partners), as opposed to the perturbative description in terms of gluons and quarks. Many physics consequences follow. In particular, we show that all the glueball propagators based presently on any version of the AdS-String/Gauge Theory Correspondence disagree by power of logarithms with the correct result implied by asymptotic freedom. Instead, the glueball propagator computed in a recently-proposed Topological Field Theory underlying large-N QCD agrees.
