Froissart bound for from CFT Mellin amplitudes

We derive bounds analogous to the Froissart bound for the absorptive part of CFTd Mellin amplitudes. Invoking the AdS/CFT correspondence, these amplitudes correspond to scattering in AdSd+1. We can take a flat space limit of the corresponding bound. We find the standard Froissart-Martin bound, including the coefficient in front for d +1 = 4

CFT d≤6, the number of subtractions needed to write a dispersion relation for the Mellin amplitude is equal to 2, for CFT d>6 the number of subtractions needed is greater than 2 and goes to infinity as d goes to infinity.
