Description |
We show how flat space S-matrix elements can be elegantly extracted from correlation functions in AdS/CFT. In particular, we show that the (d+1) dimensional flat-space amplitude of gravitons or gluons can be obtained as the coefficient of a particular singularity of the d-dimensional correlator of the stress-tensor or a conserved current Fourier transformed to momentum space. After establishing this method at tree-level, we discuss how it could be used at arbitrary order in perturbation theory. |
