Description
Dispersion relations relate different kinematic regimes of scattering amplitudes. In particular, generic properties of the microscopic dynamics constrain the possible IR physics. We present the set of constraints on EFTs with well-defined perturbative regime, coming from both positivity of the UV spectrum and full unitarity. We mention how the picture is extended at finite t and say a few words when multiple fields are involved.
