The cosmological bootstrap: inflationary correlators from symmetries and singularities

The cosmological bootstrap: inflationary correlators from symmetries and singularities

Abstract Scattering amplitudes at weak coupling are highly constrained by Lorentz invariance, locality and unitarity, and depend on model details only through coupling constants and the particle content of the theory. For example, four-particle amplitudes are analytic for contact interactions and ha...
