Description

Dispersion relations, often called Kramers-Kronig relations, exploit analyticity to reconstruct the real part of a scattering amplitude from its imaginary (or absorptive part), which is often easier to measure and or to compute. I will present a generalization which reconstructs complete four-point correlators in any conformal field theory, starting with only very limited information about their "absorptive" part. Interesting applications range from three-dimensional critical phenomena to the gauge-gravity (AdS/CFT) correspondence.
